Vanilla: Sweet—and Savory

February

Many smart gardeners are also smart chefs.

Since we've been researching edible orchids in preparation for the Chicago Botanic Garden's upcoming Orchid Show, we devote this month's edition of Smart Gardener to those gardener-chefs who love the link between the horticultural and the culinary.

Of the few orchids that are used as edibles worldwide, one is world-famous and probably already in your kitchen cabinet: Vanilla planifolia. One of the 110 species in the orchid genus Vanilla, V. planifolia is a vining orchid that's indigenous to Mexico. Its flower, a lovely greenish-white orchid flushed with yellow, produces a fruit/seedpod (technically a capsule) that, when cured and dried, is familiarly called a vanilla bean.

Vanilla was "discovered" by explorer Hernán Cortés when he encountered the Aztec nation in 1519. Montezuma, king of the Aztecs, offered the Spaniard a drink recognizably named xocolatl (pronounce the "x" as "ch").

Here is how orchid expert Ken Cameron describes the Aztec beverage in his fascinating and fact-filled book entitled Vanilla Orchids: Natural History and Cultivation:

"So important was this sacred and exclusive beverage, used to combat fatigue much as coffee is today, that as many as 2,000 cups of xocolatl were consumed each day by the royal Aztec court, with Montezuma alone drinking 50 cups per day."

The ingredients may surprise you: chocolate, of course, in the form of ground cacao seeds; corn, also ground; chili peppers; and vanilla (the fruit/seedpod, not the modern extract). Shortly after his first drink of xocolatl, Cortés conquered the Aztecs, and returned to Spain with the nation's riches…including both cacao and vanilla. That description of the drink—a bitter/savory version of the sweet hot chocolate we drink today—made us think about the many uses of vanilla in the kitchen.

Most cooks think of vanilla extract as a sort of liquid sweetener—an ingredient to be used in cookies, cakes, candies, custards, and your morning yogurt. But true vanilla is more than a sweetener. It is actually a powerful flavor enhancer, due to the 250 to 300 flavor notes that develop when the green vanilla bean (flavorless and odorless) is harvested at the appropriate ripeness, then "killed" (to stop ripening), cured and sweated, and finally dried, in a process that takes five to eight months. In essence, real vanilla can enhance the flavor of just about anything—even a bitter cacao/corn/chili pepper drink. Which brings us to the second half of our headline: savory.

How might vanilla (beans or extract) be used in savory ways?

To find out, we called Nancy Clifton, Garden program horticulturist and culinary guru.

Her suggestions sent us running for vanilla paste, a product made by Waukegan's own Nielsen-Massey—a company more than 100 years old—that makes true vanilla extracts and other flavorings. Their product has the same flavor as their vanilla extract, but the tiny vanilla seeds are visible in the pourable, brushable, thicker paste. Here is what Nancy suggests:

  • Use vanilla paste as a glaze for chicken or fish.
  • Roast butternut or acorn squash with a glaze of vanilla paste and butter.
  • Roast brussels sprouts with garlic, then finish with parmesan cheese and drizzle with vanilla.
  • In summer, grill zucchini or summer squash brushed with vanilla butter.
  • Try herb-infused (such as bay leaf) crème brûlée with vanilla paste flavoring the caramelized sugar crust.
  • Bake a parsley (or other herb-infused) cake made with vanilla; for the frosting, use goat cheese, again flavored with vanilla, as you would cream cheese. Bake it in a jellyroll pan or individual 6-inch ramekins.

Infuse 1 cup vodka with ½ to 1 cup sugar plus two vanilla beans, sliced open.

The idea of vanilla as a savory flavor enhancer is just one way of giving plants or plant parts a second look in the kitchen. Many seeds can be flavorings, too—dill, fennel, and coriander come to mind. If you're coming to the Orchid Show on February 22, check out our Seed Swap, also held at the Regenstein Center, from 3 to 5 p.m. that day.
