2 fluid ounces silver tequila (such as Patron®)
12 leaves mint
1 tablespoon white sugar
3 lime wedges
1/4 cup club soda, or as needed
Combine tequila, mint leaves, sugar, and lime wedges in a tall glass; vigorously stir the mixture, crushing mint with the back of a spoon to release oils and squeezing juice from the lemon wedges. Top with club soda and stir gently to serve.
