Vanilla – An Expensive Spice

By Maryann Readal

Vanilla, Vanilla planifolia, is The Herb Society’s Herb of the Month for December. It is the perfect month to feature vanilla, since its flavor will be a fragrant ingredient in many of the desserts that are served during the holidays. But where to begin a discussion of this historic spice, which is the second most expensive spice in the world after saffron?

Vanilla is the fruit of an orchid flower. It is a long, dark brown seed pod, which contains thousands of  tiny black seeds. Those tiny black seeds are the specks you see in good vanilla ice cream. Vanilla extract is extracted from those seed pods. The vanilla orchid grows in the tropical climates of places like Mexico, Réunion, Tahiti, and Madagascar. Today, 80% of vanilla comes from the island nations of Madagascar and nearby Réunion in the Indian Ocean. Vanilla grown in Madagascar is the most desirable and is often called “Bourbon Vanilla” (Oon, 2020). However, the vanilla vine, which grows to about 300 feet, was first grown in Mexico. At first, Mexico was the only place where vanilla grew, because it needed the Melepona bee to pollinate the flower in order to produce the seed pod. Hernán Cortéz is credited with discovering vanilla during his exploration of Central America in the 16th century, where the Aztecs combined vanilla with cocoa to create their famous drink, xocolatl. The plant was eventually brought to Europe and other tropical climates, but the plants could never produce the vanilla bean, because the Melepona bee pollinator was not present to pollinate the flowers. That is, until one day in 1841, a young boy on the Réunion island in the Indian Ocean discovered how to manually pollinate the vanilla orchid. Soon, growing pod-producing vanilla vines was possible in other tropical countries.

But the process of producing the vanilla was—and still is—a laborious one. It takes three years for a vanilla plant to bloom. Each vanilla flower opens for only one day, and hand-pollination has to be done during a very short window of time. (Watch this video to see how vanilla flowers are pollinated.) Once pollinated, it takes five to nine months for the pods to ripen. When ripe, but before the pods split open, the vanilla pods are picked by hand and then subjected to a multi-step curing process that takes another six months to a year to complete. It is only after this curing process that the vanilla bean develops its distinct vanilla fragrance and flavor. The cured beans are then shipped to an extraction facility, where the beans are ground and soaked in alcohol and water, infusing the vanilla flavor into the liquid that becomes vanilla extract. This long process is the reason for the expense of real vanilla extract.

In 2022, the price of Madagascar vanilla was between $178 and $206 per pound (Salina Wamucii, 2022) after being only $20 per pound five years before. After two devastating cyclones, which destroyed much of the vanilla crop growing in Madagascar in 2017, prices have soared. The expensive and scarce vanilla has forced farmers to imprint a code on each of their growing vanilla beans in order to deter thieves. Companies that import large quantities of vanilla have banded together to help farmers deal with the environmental problems that are affecting their vanilla vines. They decided that helping the farmers is easier than changing formulations based on a new vanilla product and changing the labels needed for a new product.

The demand for vanilla flavoring far exceeds the supply. Vanilla contains between 250-500 different flavor and fragrance components. The most prominent is vanillin, which scientists learned how to create in the laboratory in the late 19th century. Vanillin can be made from petrochemicals, from wood pulp, and from eugenol, which is a component of clove oil. This synthetic or imitation vanilla is much cheaper than the real vanilla extract made from the vanilla beans. It is most likely the one used in vanilla-flavored food products that we are familiar with. “The vast bulk, 99 percent of vanilla-flavored products on the market, from vanilla flavored vodka to vanilla wafers and vanilla pudding, don’t actually contain vanilla” (Rupp, 2014). For consumers, who are increasingly demanding natural products, vanilla made from petrochemicals or wood chips is a difficult choice to make.

So, which vanilla product should you use this holiday season—the cheaper imitation vanilla or the real, but expensive, vanilla extract? Some say that if you are baking something that requires a temperature over 300 degrees, you can just as well substitute the imitation for the real thing. But if you are making puddings, custards, or vanilla ice cream, you should use the real thing—vanilla extract.

Exploring Vanilla in the Rainforest and in the Kitchen: Part II

By Susan Belsinger

(Adapted from her article, “Exploring Rainforest Spices at Villa Vanilla,” featured in the 2019 issue of The Herbarist, the annual journal of The Herb Society of America.)

“Plain vanilla is very much like that little black cocktail dress—always welcome, simply chic, so quietly dramatic.”

                —Lisa Yockelson, from Baking by Flavor

Vanilla in the Kitchen

Although I am a chocolate lover, I have always adored the fragrance of vanilla. More than once as a child, I tasted vanilla extract straight from the bottle—knowing full well that I wouldn’t like it—I just could not resist, because it always smelled so good.   

Back in my early adult years—and the beginning of my lifetime association with natural foods, herbs, and spices—I used vanilla beyond the kitchen. I found the aroma alluring, so why not use it like perfume? I would dab it behind my ears and on my pulse points. Occasionally, I would sprinkle cinnamon or nutmeg on my hands and run them through my hair. Ah, the innocence of youth—here I thought I smelled exotic and delicious (vanilla is known as an aphrodisiac)—and most people probably thought I smelled like a cinnamon bun!

The fragrance of pure vanilla extract and the essential oil is at once exotic, tropical, warm, and sensual—a combination of flowery and resinous, with a slight hint of bitterness. Due to its enticing scent, one would think it tastes sweet and flowery, but that is not the case. We associate vanilla as being sweet because it is used in every type of confection and sweet food from cereals, buns, and cakes to cookies, ice creams, and, of course, chocolate. Some vanilla beans have that exotic flowery scent, while others smell like bitter chocolate, winey, or even slightly smoky. I think they taste fruity—rather raisin-like—sometimes flowery, smooth, and slightly sweet and resinous.

Vanilla is everywhere today—we seem to take it for granted—and it isn’t just plain old vanilla anymore. It partners with many other flavors—not just desserts—but drinks, soups, sauces, and rice dishes; with seafood, from lobster with vanilla butter to seafood salad; as a glaze for poultry and pork; in barbecue sauces and in condiments from vinaigrettes to mustard…even mashed potatoes! It makes chocolate seductive, and works well with spices—cinnamon, nutmeg, cloves, ginger—while subtly enhancing just about any baked good. It complements dairy products, coffee, and tea and brightens any fresh fruit bowl or cooked compote. Generally, vanilla highlights most foods without being too forward or overbearing.

Vanilla Products

Vanilla comes in many forms. Although vanilla pods are the source for pure vanilla extract, they aren’t commonly used by the home cook as often as the extract is used. The following list of vanilla products should help you know your beans better:

Whole Vanilla Beans 

The largest producers of Vanilla planifolia are Madagascar and Mexico, and they are renowned for growing and curing the world’s best beans. Tahitian vanilla beans, V. tahitensis, are known for their intense perfume, though they are said to be less flavorful. When purchasing whole beans, they should smell fragrant, should be a dark chocolate brown, and somewhat pliable rather than hard and dried. Store them in a tightly closed jar in a cool dark place away from light, and they should last a few years. Do not freeze or refrigerate.

Pure Vanilla Extract

To extract the flavor from vanilla beans, alcohol must be used. It is usually done with a menstruum of alcohol and water (rather like making a tincture). An extract must be 35% alcohol—the label should read “Pure Vanilla Extract.” If it is less than this, it is considered a flavoring. Read your labels: imitation vanilla is often made from artificial vanillin rather than natural vanillin, which is usually synthetically made and is a by-product of the paper industry. Mexican vanilla extract can be very good if it is pure, but beware of inexpensive extracts; it should alert you to the fact that it is probably synthetic.

Vanilla Bean Paste

This thick brown paste is made from pure vanilla extract, vanilla bean seeds, sugar, water, and a natural thickener, gum tragacanth. The label states equivalents of 1 tablespoon of vanilla bean paste equals 1 vanilla bean or 1 tablespoon of pure vanilla extract. It is sweeter than vanilla extract and much thicker but can be used anywhere you would use vanilla extract. I use it in all kinds of baked goods from muffins and cakes to cookies and bars. It elevates oatmeal to another level when combined with fresh sliced peaches or dried blueberries or cherries and maple syrup.

Pure Vanilla Powder

This fine-textured powder is made from vanilla bean extractives and maltodextrin and is alcohol-free; it can be used in place of vanilla extract. Upon tasting it, it is slightly sweet and leaves a residue on the tongue. It can be used for dry mixtures and liquid- or color-sensitive products. You can sprinkle it on fruit or in your coffee, tea, or cocoa. I have used it in whipping cream, buttercream, and angel food cake. 

Vanilla Sugar

Vanilla sugar has been made for centuries by placing a vanilla bean in sugar to give it a lovely vanilla perfume and flavor. Nowadays, vanilla sugar can be purchased commercially, but you can easily make your own. 

For those willing to venture out from the grocery store offerings, below are some easy-to-make vanilla staple recipes.

Vanilla Bean Syrup

When I was a kid my favorite snowball flavor was Egg Custard. I could never figure out why it was called that—it tasted like vanilla to me. This syrup reminds me of that egg custard flavor. In fact, try it over shaved ice for a snowball. It also makes an excellent vanilla bean soda when mixed with sparkling water or served over ice cream for a vanilla ice cream soda. Use it with coffee to make a vanilla latte or as a sweetener in your hot or iced tea. It can be used in fruit salads, or drizzled over baked goods warm from the oven, like pound cake, scones, breads, or muffins. My kids used to object to the aesthetics of the little black seeds—I rather like them— so if they bother you, strain the syrup through fine cheesecloth or muslin to remove them. This can be made with maple syrup instead of sugar; however, the maple flavor will dominate.

(Makes a little more than 2 cups)

1 cup organic sugar

1 1/2 cups water

1 vanilla bean

Split the vanilla bean lengthwise and cut it into thirds crosswise.  

Combine the sugar and water in a heavy-bottomed pan and place over medium heat. Bring to a boil, add the vanilla bean pieces, and stir. Reduce heat, cover, and barely simmer for about 5 minutes. Remove from heat and let cool, covered.  

Remove vanilla bean and reserve the pieces—they can be dried and used to make vanilla sugar. Pour the syrup into a bottle or jar and label. It will keep in the refrigerator for one month or can be frozen for about six months. 

Homemade Vanilla Extract

Most pure vanilla extract is about 35% alcohol and contains water, sugar, and vanilla bean extractives. It is pretty easy to make your own version. It won’t taste just like the commercial brands—it probably won’t be quite as intense in vanilla flavor, but I find it very satisfactory. Vodka will allow the most vanilla bean flavor to come through. However, I often make mine with brandy or rum because I like the flavor of them. Remember, you only use 1 to 2 teaspoons in a recipe, so a little goes a long way. Try experimenting to see what you like best.  

(Makes about 1 cup or an 8-ounce bottle, or halve the recipe for a smaller amount.)

2 or 3 vanilla beans

8 ounces of vodka, rum, or brandy

Cut the vanilla beans in half crosswise and then in half lengthwise. Put them into a clean, dark glass, 8-ounce bottle. (I save my old vanilla extract bottles for this purpose.) Using a funnel, pour the alcohol into the bottle. Cap the bottle and shake for a minute or two. Label and date the bottle. Place in a cool place out of direct light.  

The extract should be shaken once a day, at least for the first week. I do it whenever I go into the pantry and think about it. I usually uncap it and take a whiff—it is a form of kitchen aromatherapy for me, the wealth of the cook. You can use it after a week, but it is best after three or four weeks and gets better as it ages.

The longer it sits, the more intense the flavor. While commercial vanilla extract has the beans removed, I leave the beans in the bottle and as I use the extract, I top it off with more alcohol. Occasionally, I add another bean.

Vanilla Vinegar

Once you have this on hand, you will begin to use it in many dishes, and you will wonder why you never had it before. I use organic apple cider, umeboshi plum, rice wine, or white wine vinegar, which are naturally made and good tasting. Do not make this with distilled vinegar. I often make fresh fruited vanilla vinegars, with peach or raspberry being my favorites. (Add 1 whole, ripe peach, peeled and sliced, or 1-pint raspberries to the jar when combining the vinegar and vanilla bean, and let macerate for at least three to four weeks. Strain, if desired.) I use vanilla-flavored vinegar in small amounts in vinaigrettes, dressings, fruit and vegetable salads, and sauces. I particularly love what it does to Waldorf salad.

(Makes 1 pint)

1 pint good-quality vinegar, preferably organic

1 whole vanilla bean

Cut the vanilla bean in half crosswise and then in half lengthwise. Put the pieces into a clean, 1-pint bottle. (I save used vinegar or soy sauce bottles for this purpose.) Using a funnel, pour the vinegar into the bottle. Cap the bottle and shake for a minute or two. Label and date the bottle. I leave the bottle on the kitchen counter for about two weeks and shake it every day, twice a day. You can use it after a week, but it is best after 3 or 4 weeks.  

The longer it sits, the better the flavor. As the vinegar gets used up, I top it off with a little more vinegar. I also add pieces of dried vanilla bean that I have already used.

Preparing Vanilla-Scented Sugar

Scented sugars can easily be made the same way that the Europeans have been making vanilla sugar for years. Placing a vanilla bean in a pint jar of sugar transforms the sugar into a pleasing, fragrant addition to beverages, cakes, cookies, custards, whipping cream, and all sorts of sweets. Sprinkle a little on fruit and toss it, or stir some into your tea or coffee cup. If you do a lot of baking, make this in larger quantities—say a quart or half-gallon jar— as you will find that you use it often.

(Makes 2 cups)

About 2 cups organic sugar

1 vanilla bean, cut into 3 or 4 pieces

To prepare scented sugar, use a clean pint jar with a tight-fitting lid. Fill the jar about one-third full with sugar, and place one or two pieces of vanilla bean in the sugar. Cover the vanilla bean with additional sugar so that the jar is two-thirds full, add another piece or two, and cover with sugar to fill the jar, leaving about 1/2-inch headspace. Shake the jar and place on a shelf in a cool, dark place.  

The sugar will be ready to use in two to three weeks and will become more flavorful with age. As the sugar is consumed, add more plain sugar to take its place and it will take on the fragrance in the jar. I also add dried pieces of vanilla beans that I have already used for another purpose.

Since vanilla beans contain moisture, the sugar will absorb some of it and perhaps cake together, or even harden. If this happens, just use firm pressure to crumble it with either your hands or the back of a wooden spoon.

Hot Vanilla Milk

Make this milk when you can’t sleep and cocoa might keep you awake, or for those rare individuals who don’t like the flavor of chocolate. You can use sugar to sweeten, but I really like the maple syrup best; go light on the sweetener as you hardly need any. If you don’t have vanilla bean paste, use a generous teaspoon pure vanilla extract and 1 1/2 teaspoons sweetener, or add 2 tablespoons of Vanilla Syrup.

(Makes 1 cup, easily doubled)

1 cup milk (whole, 1 or 2 %, or oat or almond milk)

1 teaspoon vanilla bean paste

1 teaspoon pure maple syrup or organic sugar

In a small saucepan, bring the milk almost to a simmer over medium low heat. Stir in the vanilla bean paste and sweetener and blend until it is dissolved. If you are using extract, remove the warmed milk from the heat and add the extract and sweetener; stir to dissolve. 

Taste the milk—if you have a sweet tooth, you may want to add another teaspoon of sweetener. Pour the vanilla milk into a mug. Inhale the vanilla aroma before you take your first sip. Relax and enjoy. 

Vanilla Butter Cookies with Cacao Nibs

This is a simple butter cookie recipe (from not just desserts—sweet herbal recipes), though instead of using herbs, cacao bean nibs are added. They are further enhanced by using vanilla bean sugar as well as pure vanilla extract; the vanilla compliments the flavor of cacao. These cookies keep well in a tin for a week or two, and they also freeze well.

(Makes about 5 dozen cookies)

12 tablespoons unsalted butter, softened

1 cup vanilla bean sugar

1 extra-large egg

1 1/2 teaspoons pure vanilla extract

1 cup unbleached white flour

1 cup whole-wheat pastry flour

1/2 teaspoon salt

1/2 cup cacao nibs

In the bowl of a food processor, cream the butter and sugar. When combined, beat in the egg and vanilla extract. Gradually mix in the flour and salt. Add cacao nibs and pulse just to combine. 

The dough will be soft. Divide the dough into two parts. Using plastic wrap to shape the dough, roll each part into a cylinder about 1 1/2-inches in diameter. Chill the rolls for an hour, or place in the freezer for 20 to 30 minutes.      

Preheat the oven to 350°F. Remove the plastic wrap, and slice the dough into 1/4-inch rounds. Place the cookies on ungreased baking sheets, and bake for about 10 minutes until the cookies are nice and brown.  Remove the cookies from the baking sheets while they are hot and cool on racks.

Exploring Vanilla in the Rainforest and in the Kitchen: Part I

By Susan Belsinger

(Adapted from her article, “Exploring Rainforest Spices at Villa Vanilla,” featured in the 2019 issue of The Herbarist, the annual journal of The Herb Society of America.)

Vanilla in the Rainforest

Before going to Costa Rica, I researched gardens, restaurants, herbs, spices, botanicals and the rainforest—places where I wanted to go, see, and experience. Once I visited Villa Vanilla’s website, https://www.rainforestspices.com/, I knew that I had to go there. I made reservations for the farm tour in advance. It was one of my favorite things in Costa Rica—I loved seeing the tropical spice plants up close and personal—and I got to smell and taste so many things, which was a memorable sensory experience! 

During the half day Spice Plantation Tour, visitors experience the sights, tastes, and aromas of vanilla, cinnamon, pepper, and other tropical spices, essential oil plants, and a wide variety of tropical ornamental plants. The tour begins and ends at the post-harvest warehouse, where my eyes feasted on the spectacle of the ground covered with burlap sacks, which were spread with vanilla beans in various stages of fermentation and curing, and my nose filled with the delightfully overwhelming perfume of vanilla.

Vanilla is the main crop that is cultivated on this farm, with Ceylon cinnamon as a secondary crop. However, they also cultivate cacao, pepper, allspice, cloves, nutmeg, chiles, turmeric, cardamom, ginger (mostly ornamental), and a large number of epiphytes. 

On our tour, we sampled delicious treats made by the chef, who used the farm’s spices to titillate our taste buds. To cool off, we first had a glass of chilled hibiscus infusion while gazing out at the tropical paradise. The next sample was a lovely, smooth vanilla bean custard, not too sweet, with a creamy, melt-in-your-mouth texture. We were served a demitasse of hot chocolate flavored with a hint of cinnamon and chile accompanied by a crunchy, vanilla shortbread cookie speckled with cacao nibs. And the grand finale was a scoop of homemade vanilla bean ice cream made with farm fresh milk and cream from the farm’s own dairy cow. 

After visiting the Spice Shoppe, we walked back to the small warehouse where we were able to view different spices in various stages of drying. Our guide described and showed us some of the processes of harvesting and processing both vanilla and cacao pods, and we saw Ceylon cinnamon being barked. 

We learned about the process of the vanilla bean from harvest to cured, saleable bean. Once the plant has produced the green pods, they swell as they mature. When they are ready to harvest, they pull off easily from the stem. Green pods are placed in a large, clear plastic bag, which begins the fermentation process. Then they are laid outdoors in the sun every morning for four hours. Next, they are placed in insulated boxes while they are still warm from the sun and brought inside the warehouse for twenty hours. This is repeated every day for about three to four days. This process of sweating the beans in the sun makes a superior fermented end-product. (In other parts of the world, green beans are dropped in boiling water rather than curing in the sun.) After a week, the pods have turned brown, and they are removed from the plastic bags and spread out on burlap sacks. The four hours of sun/twenty hours in the dark process is continued for another three to four weeks until the pods have begun to shrivel and have lost about 80% of their original weight. Then they are left to cure—and this time varies among farmers—from nine months to two years. Villa Vanilla cures their beans for two years for best flavor and quality.

After curing, the beans are graded and separated according to size—there are about four sizes from thin to medium to large and extra-large. An extra-large bean is something to behold indeed! They are magnificent, thick and plump and slightly moist, bursting with the mouthwatering and intoxicating, inimitable scent of vanilla. 

Vanilla’s Aromatic Pedigree

The vanilla plant is a tropical vine that can reach a length of over one hundred feet. It belongs to one of the oldest and largest groups of flowering plants—the orchids (Orchidaceae)—currently known to contain more than twenty-five thousand species and counting. Of all the orchids, the Vanilla genus is the only one that produces an agriculturally valuable crop separate from the rare, hothouse exotic orchids cultivated and traded for their beautiful, colorful flowers. The vanilla orchid has its own appeal: a fruit with a scent so unique, so distinctive to the human palate that it was once worth its weight in silver.

The vanilla orchid’s flower is not showy; it has only a slight scent with no element of vanilla flavor or aroma. When its pale-yellow flowers are pollinated, the ovaries swell and develop into the fruits we call “pods” or “beans,” just like extra-long green beans. Pollination in the wild is very iffy, so most growers hand pollinate to ensure a viable crop. This is very labor intensive and has to be done when the flower is just open, which is a very brief window of time–literally a few hours on a single day. Each pod contains tens of thousands of tiny black seeds. The growing process lasts up to nine months, but only when the pods turn brown after being dried and cured do they develop the distinctive aroma we call “vanilla.” Drying, curing, and conditioning the pods is an art, which, if done properly, takes at least another nine months. Understandably, vanilla is one of the most labor-intensive agricultural products in the world. 

There are more than a hundred different species of vanilla orchid, and they grow all over the tropics with the exception of Australia. All of the vanilla orchids produce fruits containing seeds, but only a few species bear the large aromatic pods that can be used commercially. Virtually all of the cultivated vanilla in the world today comes from just one species, Vanilla planifolia (sometimes called Vanilla fragrans), a plant indigenous to Central America, and particularly the south-eastern part of Mexico. At least two other species, V. pompona and V. tahitensis, also provide a serviceable culinary pod, although they are not as readily obtainable, and they produce a different flavor and aroma to the V. planifolia. 

Stay tuned for Vanilla Part II, including recipes from Susan, coming 8 March, 2021!
