Ingredients

• Ingredients
  1. 2 cups water
  2. 1/2 cup sugar
  3. 2 cups (packed) basil leaves and small sprigs
  4. 1 cup (packed) cilantro leaves and small sprigs
  5. 1 cup (packed) mint leaves and small sprigs
  6. 2 tablespoons tarragon leaves
  7. 2 teaspoons finely grated lemon zest
  8. 1 tablespoon fresh lemon juice
  9. Cold club soda
  10. Lemon twists and mint sprigs, for garnish

Directions

1. In a medium saucepan, combine the water and sugar and bring to a boil, stirring with a wooden spoon until the sugar dissolves. Reduce the heat to moderate and simmer for 5 minutes; let the sugar syrup cool.
2. In a blender or food processor, combine the sugar syrup with the basil, cilantro, mint, tarragon, lemon zest and lemon juice and puree. Let stand for 1 hour, then strain through a coarse sieve, pressing on the solids with the back of a spoon to extract as much liquid as possible.
3. For each drink, pour 1/4 cup of the fresh herb syrup over cracked ice and fill with club soda. Garnish the drinks with a lemon twist and mint sprigs and serve.

Make Ahead

The herb syrup can be refrigerated overnight.
