Sourcing and Storing Fresh Lemon Balm
The best way to enjoy lemon balm is when it is freshly harvested, as its potent oils and flavor diminish when dried. The plant, known scientifically as Melissa officinalis, is an easy-to-grow perennial and a prolific spreader, making it simple to cultivate at home. You can also find it at farmers' markets during its growing season. For the best flavor, harvest the leaves before the plant flowers.
To store freshly cut lemon balm, you can treat it like a bouquet of flowers. Simply place the stems in a jar of cool water and cover the leaves loosely with a plastic bag to retain moisture. Stored this way in the refrigerator, it can stay fresh for up to two weeks. For longer-term storage, consider freezing the leaves in oil or drying them for future use.
Culinary Uses and Preparation Methods
Fresh lemon balm's versatility makes it a fantastic addition to both sweet and savory dishes. Its citrusy, mint-like flavor can be used as a substitute for lemon zest in many recipes or to infuse liquids with a delicate aroma.
Refreshing Beverages
Infusing fresh lemon balm into drinks is one of the simplest and most common preparation methods. A classic herbal tea is a wonderful way to enjoy its calming properties.
Fresh Lemon Balm Tea
- Bring 4 cups of water to a boil.
- Add 20-30 fresh lemon balm leaves to a teapot.
- Pour the boiling water over the leaves and steep for 10 minutes.
- Strain and serve, with honey or lemon to taste.
For a refreshing iced tea, simply chill the steeped tea and serve over ice. You can also muddle fresh lemon balm into cocktails like mojitos or gin and tonics for an herbaceous twist.
Savory Dishes and Sauces
Fresh lemon balm adds a bright, zesty note to savory meals. It pairs particularly well with chicken and fish.
- Pesto: Substitute fresh lemon balm for some or all of the basil in a traditional pesto recipe. It's delicious on pasta, fish, or shrimp.
- Herb Butter: Mince the fresh leaves and mix them into softened butter along with a pinch of salt and pepper. This compound butter is excellent on corn, steamed vegetables, or grilled meat.
- Salads: Toss a few finely chopped leaves into your favorite fruit or garden salad for an extra burst of flavor.
- Marinades and Dressings: Infuse fresh lemon balm into vinegar or oil to create a light, citrusy vinaigrette for salads and marinades.
Sweet Treats and Desserts
Lemon balm's flavor complements sweet dishes beautifully, enhancing fruit flavors and adding a touch of sophistication.
- Simple Syrup: Gently heat equal parts water and sugar with fresh lemon balm leaves until the sugar dissolves. Strain and cool. Use this syrup to sweeten beverages, fruit salads, or sorbets.
- Infused Desserts: The leaves can be used to infuse flavor into creams for desserts like custards, ice cream, and whipped cream.

Potential Health Benefits and Cautions
Lemon balm is known for its mild sedative and calming effects and has been traditionally used to address a range of issues from stress and anxiety to digestive problems. The herb contains chemicals that may also offer antiviral and antimicrobial properties. However, it's important to be aware of potential interactions and side effects.
Possible Side Effects and Interactions
