Everything You Need to Know About Cooking and Baking with Lavender
Crushing a fresh sprig of lavender releases a scent that is familiar and intense, and an instant tonic. Traditionally the defining ingredient in soaps, essential oils, and sachets to keep linen fresh, the perfumed herb is enjoying a culinary moment. But the use of lavender as an edible herb is a surprisingly recent development given its ancient pedigree as a perfume and medicine and its provenance (the Mediterranean). For that reason, guidance can be helpful. Deployed in moderation and with an appreciation for ingredient-pairing, using lavender in food can add an exciting new dimension to your meals, from lavender cocktails right through to aromatic desserts.
Along with some more-familiar woody edible herbs in the Lamiaceae family, like oregano, rosemary, sage, savory, and thyme, lavender is native to the scrubby edges of Mediterranean. You might suddenly become aware of its penetrating scent as you crush it underfoot while climbing a dry and rocky slope in the Atlas Mountains, throughout Spain, or the south of France. The wild, tenacious plants, adapted to parched summers and wet winters, look very different from the lush perennials that grow in gardens or in the iconic lavender fields were they are cultivated for the essential oil market.
Like those herbal staples, lavender has cosmetic and medicinal properties that endeared it to Egyptians, Greeks, and Romans (the latter of which sprinkled it in their baths). They valued the herb well before its phytochemistry could be analyzed: Lavender contains linalol, a terpene alcohol that is antimicrobial. This means that in therapeutic doses it can be medicinal, and in concentrated form (like essential oils), toxic if ingested. When it comes to culinary purposes, relatively small amounts of leaves or flowers are called for and are considered safe, as well as conducive to happy hums around the dinner table.
What Part of Lavender Can Be Eaten?
Think rosemary: We use its potent, needle-like leaves, while its gorgeous flowers are a seasonal bonus. Lavender leaves are edible and very strongly flavored. If using the flowers, strip them from the spike, or use them whole. Dried lavender retains its aroma and flavor exceptionally well (like any woody herb) and lasts for many months in an airtight jar. If you substitute fresh lavender for dried, increase the quantity called for in a recipe by three (one teaspoon dried lavender equals about three teaspoons fresh).
You can find dried lavender for culinary use available online. It's also possible to find fresh lavender at farmers' markets, but you'll want to ask if it has been grown organically. And if you would like to grow your own lavender and need some tips, try our guide. (It's not hard but lavender needs full sun and likes to dry out between waterings.) Bear in mind that plants at nurseries may have been treated with herbicides so don't consume them at once, when transplanting to your own garden space.
How to Use Lavender in Cooking
As a jumping-off point for thinking of how to use lavender with food (or drink), rosemary—again—is a helpful guide. It is piercingly pungent and works in recipes that are either strongly savory (roast leg of lamb comes to mind) or sweet and fruity (infused in dessert wine with oranges, for instance). And then there are rosemary cocktails. In each case, substitute lavender for the rosemary, and ask your taste buds and nose what they think. We predict that they will be very happy.
But we also have a slew of lavender recipes to help you on your way. Lavender salt is a versatile pantry basic—a rub for grilled meats as well as a delicious seasoning for roasted root vegetables. Its counterpart is, of course, is lavender sugar! Then there's lavender honey, which is made by infusing a neutral honey with fresh or dried lavender. Use the perfumed honey in sauces and pan juices, stir it into a soothing cup of hot black tea, shake it up with gin and lemon juice (citrus with lavender is generally a great combination), drizzle it over a platter of fruit for dessert, flavor a decadent three-cheese cake with it, and definitely make our lavender honey ice cream.
