The Edible Parts of the Lemon Balm Plant
Lemon balm (Melissa officinalis) is a well-known member of the mint family, identifiable by its square stems and distinct lemony scent. Unlike some herbs where only specific parts are used, the entire lemon balm plant is considered edible. However, the intensity of flavor and preferred use varies significantly between the leaves, stems, and flowers. By understanding these differences, you can better harness this versatile herb in your kitchen.
Leaves: The Flavor Powerhouse
The leaves are undoubtedly the most popular and flavorful part of the lemon balm plant, containing the highest concentration of its volatile oils. They possess a strong, sweet, and aromatic citrus flavor with hints of mint, making them ideal for a wide range of culinary applications.
- Fresh: Best used in salads, dressings, marinades, and as a garnish for sweet and savory dishes. When used fresh, the flavor is most vibrant and potent. Young, tender leaves harvested in the spring offer the best taste.
- Dried: Retain a good amount of their flavor and are excellent for brewing herbal teas and infusions. For optimal flavor, it is best to dry them properly and store them away from light and heat.
Tender Stems: A Milder Alternative
The stems of the lemon balm plant are also edible, though they are less commonly used than the leaves due to their woody texture and milder flavor. The younger, more tender stems can be used, while the thicker, more fibrous stalks are better off discarded for most recipes.
- Infusions and Syrups: The stems can be included with leaves when making infused waters, herbal syrups, or vinegars, where they contribute a subtle lemon background note without overpowering the flavor profile.
- Herbal Teas: When making large batches of tea, including the tender stems adds bulk and helps to extract the flavor from the leaves more efficiently.
Delicate Flowers: A Garnish with Flavor
Lemon balm flowers are also edible and, like the leaves, carry a pleasant, sweet, and delicate lemony flavor. These small, white or pale pink flowers appear from June to September and serve as an attractive and flavorful garnish.
- Salads and Desserts: They can be sprinkled over green salads, fruit salads, ice cream, or cakes for a burst of flavor and visual appeal.
- Infused Beverages: The flowers can also be added to drinks like lemonade or sparkling water for a subtle flavor infusion.
Harvesting and Preparing Lemon Balm
Proper harvesting is key to getting the most flavor out of your lemon balm. Here are a few tips to ensure your harvest is successful.
- Harvest in the morning: The concentration of volatile oils is highest in the leaves early in the day, after the dew has dried.
- Before flowering: For the most potent flavor, harvest the leaves before the plant begins to flower. Cutting back the plant regularly encourages new, flavorful growth.
- Handle gently: To avoid bruising, handle the fresh leaves gently. They are best used soon after picking, but can be frozen in water in ice cube trays for later use.

Culinary Applications for Edible Lemon Balm
With its bright flavor, lemon balm is a versatile ingredient that works well in both sweet and savory recipes.
Herbal Teas and Infusions
- Calming Tea: A relaxing herbal tea can be made with fresh or dried lemon balm leaves, helping to soothe anxiety and aid digestion. Combine with other herbs like mint or chamomile for a custom blend.
- Refreshing Infused Water: Add a few sprigs of fresh lemon balm to a pitcher of cold water for a light, refreshing summer drink.
Savory Dishes
- Pesto: Substitute or combine lemon balm leaves with basil to create a bright, citrusy pesto, excellent for pasta or as a spread.
- Marinades and Sauces: Finely chopped lemon balm can be used in marinades for fish or chicken, or added to salsas and dressings.
Sweet Treats and Beverages
- Desserts: Mince fresh leaves to incorporate into sorbet, ice cream, cakes, and other fruit desserts. Candied lemon balm leaves are also a decorative and tasty option.
- Cocktails and Syrups: Infuse lemon balm into a simple syrup to create cocktails or cordials with a uniquely fresh, botanical flavor.
The Fresh vs. Dried Lemon Balm Debate
The form in which you use lemon balm largely depends on your intended application and desired flavor intensity. Fresh leaves are undeniably superior for a vibrant citrus taste.
- Fresh lemon balm is best for recipes where its bright, aromatic flavor is the star, such as in salads, dressings, and garnishes. The aroma is also much more pronounced with fresh leaves.
- Dried lemon balm is excellent for infusions and teas, where the extraction process helps to release the flavor. When dried, lemon balm loses some of its delicate flavor and is less ideal for recipes that depend on that specific freshness.
Conclusion
From the tender leaves used in teas and pesto to the decorative flowers and mild stems, almost every part of the lemon balm plant can be utilized in the kitchen. The key is to understand the different flavor profiles and textures to make the most of this prolific and aromatic herb. Whether fresh or dried, lemon balm offers a bright, lemony zest that can enhance a wide array of dishes and beverages. Experimenting with each part of the plant allows for a deeper appreciation of its culinary versatility.
