Certain types of lavender flowers (buds) are absolutely safe to eat in cooking and can add a unique, aromatic, and delicious floral note to both sweet and savory dishes.
However, there are a few very important distinctions to keep in mind to ensure safety and good flavor:
-
The Right Type of Lavender is Crucial:
-
Best for Culinary Use: English Lavender (Lavandula angustifolia). This is the go-to species for cooking. It has a sweeter, more floral, and less camphorous (medicinal/soapy) flavor compared to other varieties. Popular culinary cultivars within Lavandula angustifolia include 'Munstead', 'Hidcote', 'Royal Velvet', and 'Folgate'.
-
Generally Avoid for Cooking: Lavandin (Lavandula x intermedia) and Spanish Lavender (Lavandula stoechas). These varieties are often grown for their essential oil yield or ornamental value. They have a higher camphor content, which can result in a more bitter, resinous, or "soapy" taste in food. While not necessarily "toxic" in small amounts, they won't make your food taste good.
-
-
Use the Flowers/Buds, Not Essential Oil (Unless Specifically Food Grade):
-
Edible Part: When cooking with lavender, you use the dried or fresh flower buds. These are the parts that impart the delicate flavor.
-
Lavender Essential Oil is Highly Concentrated: Most lavender essential oils are NOT intended for internal consumption. Ingesting them can be harmful due to their highly concentrated nature, even if they are pure or organic. They are formulated for aromatherapy or topical use.
-
"Food Grade" Essential Oils: While some essential oils are specifically certified as "food grade" or "culinary grade" and can be used in extremely minute quantities (like a toothpick swirl in a large batch), it's safer and generally recommended for beginners to stick to using the actual dried or fresh lavender buds.

-
Source Matters:
-
Culinary-Grade Lavender: Purchase lavender specifically labeled as "culinary lavender" from reputable herb shops, gourmet food stores, or farmers' markets. This ensures it's the correct variety and has been processed for food use.
-
Garden Lavender: If you're using lavender from your own garden, make sure you know the exact species (Lavandula angustifolia) and confirm it has not been treated with any pesticides or chemical sprays. Always wash the buds gently before use.
-
-
Use Sparingly:
-
Lavender has a very strong flavor. A little goes a long way. Too much can overpower a dish and result in that "soapy" taste people sometimes associate with badly used lavender.
-
Rule of Thumb: Start with a very small amount (e.g., 1/4 to 1/2 teaspoon of dried buds for a recipe serving several people) and add more to taste. The goal is a subtle floral background note, not an overwhelming flavor.
-
Common Culinary Uses:
Lavender can be used in a surprising variety of dishes:
-
Sweet: Cookies, scones, cakes, ice cream, sorbets, simple syrups for drinks, jams, honey infusions, crème brûlée.
-
Savory: Herbes de Provence blends (often with rosemary, thyme, oregano), rubs for roasted meats (especially lamb or chicken), marinades, savory sauces, roasted vegetables.
-
Beverages: Teas (hot or iced), lemonades, cocktails, lattes.
By choosing the right type of lavender (English lavender buds), sourcing it responsibly, and using it in moderation, you can safely and deliciously incorporate this aromatic herb into your cooking.
