How to Make Lemon Basil Herbal Soda
This recipe uses just four simple ingredients:
- Fresh lemon basil leaves and stems
- 1 cup water
- 1 cup sugar
- Club soda or seltzer water
Simple, fresh, and delicious.
Lemon basil has a bright, citrusy aroma that’s different from other basil varieties. If you haven’t tried it, consider growing a plant—it’s easy to cultivate and often self-seeds. Its lemon-forward flavor with a hint of sweet basil makes it ideal for flavorful syrups and beverages.
I grow several basils in containers: lemon, sweet, and cinnamon basil. When your herb garden is abundant, turning fresh leaves into a homemade herbal soda is a wonderful way to showcase them. Guests are always delighted when served a homemade drink like this Lemon Basil Herbal Soda.
Recipes Using Your Herb Plants
Herbal sodas are versatile — many herbs work well. Use this lemon basil version as a template and experiment with other herbs you grow. The process is the same: make a simple syrup infused with fresh herbs, then mix with carbonated water.
I waited until my lemon basil was plentiful before harvesting a cup of leaves and stems to make this batch of soda. The result was a bright, aromatic syrup that transforms ordinary seltzer into something special.
How To Make Herbal Simple Syrup
Follow these steps to make the lemon basil simple syrup for your soda:
- Harvest one cup of lemon basil leaves and stems early in the morning when the essential oils are strongest.
- Rinse the herbs in cool water and drain.
- In a medium saucepan, combine 1 cup water and 1 cup granulated sugar. Bring to a boil, stirring until the sugar dissolves, then remove from heat.
- Allow the syrup to cool about 20 minutes so it is warm but not hot.
- Crush the lemon basil leaves and stems lightly, then add them to the syrup. Stir and press the herbs down so they are submerged.
- Let the mixture steep for one hour to extract the flavor.
- After steeping, strain the syrup through cheesecloth or a coffee filter to remove all bits of herb—any remaining pieces can promote mold during storage.
- Pour the infused syrup into a jar with a lid and refrigerate. It will keep for a couple of weeks, though it may be enjoyed long before then.
To assemble a glass of lemon basil herbal soda, add 2 to 4 tablespoons of the lemon basil syrup to a glass filled with ice. Top with club soda or seltzer, stir gently, and taste. Adjust syrup amount to your preferred sweetness and intensity of flavor.
Take a sip and enjoy—the drink is bright, slightly sweet, and perfectly refreshing.
