There is something deeply revitalizing about an icy green garden soda. Stock a batch of this syrup and a bottle of sparkling water in your fridge, and you’ll be ready for all invited (and uninvited) summer guests.

During the summer months, I always like to have a fresh mixer on hand for making sodas and cocktails. You can find this garden sorrel syrup in the door of my fridge from June through September. Sometimes I go full tilt sorrel in this recipe for a clean, tart, green treat, but often I’ll add other kitchen garden herbs like mint, lavender and thyme or sage for nuance. What can I say? I live for variety—especially in the kitchen.
