In a blender or food processor, purée the strawberries and basil together until smooth. You should end up with about 4 ounces total.

In four highball glasses, add 1 oz. strawberry basil purée, 1/2 oz. lime juice, 1/2 oz. simple syrup, 1 1/2 oz. gin, and 1/2 oz. elderflower liqueur to each glass. Stir until combined.

Fill the glasses with ice. Top with soda water. Garnish with strawberries, basil, etc. Stir the strawberry gin smashes right before drinking. Enjoy!

Place 1/4 cup of sliced strawberries into each highball glass. Muddle until the strawberries are juicy and smooth. Add 2 basil leaves to each highball glass and muddle just a bit to release the flavor of the herb.

To each glass, add 1/2 oz. lime juice, 1/2 oz. simple syrup, 1 1/2 oz. gin, and 1/2 oz. elderflower liqueur. Stir.

Fill the glass with ice and top with club soda. Garnish, if desired. Give it a stir right before enjoying.
