The Unique Flavor Profile of Sweet Woodruff
Sweet woodruff, scientifically known as Galium odoratum, is a woodland perennial that offers a unique culinary experience. When fresh, the leaves have a mild, grassy flavor. However, upon wilting and drying, the plant's aromatic potential is unlocked. The dried herb develops a distinctive, sweet fragrance reminiscent of vanilla, fresh hay, and notes of cinnamon. This aroma comes from the natural chemical compound coumarin. Its unique and potent flavor makes it a fantastic, and often more interesting, alternative to standard vanilla in many recipes.
Essential Safety: Harvesting and Preparing Sweet Woodruff
Enjoying sweet woodruff requires careful preparation to ensure safety and to achieve its desired flavor.
Harvesting at the Right Time
The flavor and aroma of sweet woodruff are most intense right before or during its flowering period, typically in May. Look for its delicate white star-shaped flowers that appear clustered at the top of the plant. Harvest the entire plant just above the lowest whorl of leaves to allow it to regrow.
Proper Drying is Critical
This is the most crucial step for safe consumption. Damp drying can convert coumarin into dicoumarol, which can interfere with blood clotting and is harmful in large quantities.
- Gather the harvested stems into small bunches.
- Hang the bunches in a warm, dry, and well-ventilated area out of direct sunlight.
- Alternatively, spread the stems in a single layer on a mesh screen or clean baking sheet.
- Ensure they dry quickly and completely. The dried herb should be stored in an airtight container in a cool, dark place.
A Caution on Dosage
While sweet woodruff contains coumarin, the amount found in the small quantities used for cooking is not considered dangerous for humans. However, excessive consumption of large, medicinal doses can raise health concerns and cause side effects like headaches. Moderate use in culinary applications is key.

How to Use Sweet Woodruff in the Kitchen
Sweet woodruff is most often used as a flavoring agent through infusion rather than eaten directly. Its potent flavor requires only small amounts.
Infusions
Create aromatic liquids by steeping dried sweet woodruff in various bases:
- Cream or Milk: Infuse cream or milk for an hour or two to use in custards, puddings, panna cotta, and ice cream.
- Alcohol: Steep dried woodruff in white wine to create the traditional German Maibowle (May wine), or use it in vodka or brandy infusions.
- Simple Syrup: Infuse a sugar and water syrup to create a versatile sweetener for cocktails, sodas, and desserts.
Syrups
A sweet woodruff syrup is perfect for flavoring cold drinks or drizzling over sweets.
- Ingredients: 1 cup water, 1 cup sugar, a handful of dried sweet woodruff stems and flowers.
- Instructions: Combine water and sugar in a saucepan. Heat gently until sugar is dissolved. Add sweet woodruff and bring to a simmer. Remove from heat and let steep for 30 minutes. Strain out the herb and store the syrup in an airtight bottle in the refrigerator.
Desserts and Culinary Pairings
Sweet woodruff's vanilla-like notes pair exceptionally well with fruits and creamy textures:
- Pairings: Excellent with strawberries, apples, and rhubarb.
- Desserts: Use infused cream for a distinctive panna cotta or crème brûlée.
- Savory: The Danes have used it with beets and white meats like chicken.
