Aside from banana, we can't think of a fruit that wouldn't be good in this drink.
Ingredients
1 1/4 cups chilled gin
1 cup chilled fresh lemon juice
1/2 cup sugar
2 lemons, cut into wedges
1 mango, cut into 1/2" wedges
1/2 English hothouse cucumber, thinly sliced
6 sprigs mint
1 (4" piece) ginger, peeled, thinly sliced
1 cup fresh raspberries
1 cup fresh strawberries, hulled, quartered
Club soda (for serving)
Directions
Combine gin, lemon juice, and sugar in a pitcher or large measuring glass and stir to dissolve sugar; refrigerate gin mixture if not making drinks right away.
Gin mixture can be made 1 day ahead. Cover and chill.
When ready to serve, arrange lemon wedges, mango, cucumber, mint sprigs, ginger, raspberries, and strawberries on a platter or in separate bowls and set out alongside gin mixture, club soda, and a bucket of ice.
For each cocktail, muddle ingredients of your choice (mix and match!) in a Collins glass. Fill with ice, then add 1/4 cup gin mixture and top off with club soda.
