Step 1

Add the mint leaves, sugar, strawberry slices, and grapefruit slices to a large cocktail glass. Muddle, avoiding the pith of the grapefruit, until the sugar is dissolved.

Step 2

Fill your glass with ice. Add the rum and the grapefruit juice then top with club soda to fill the glass (you may not need the full 2oz). Gently stir, keeping the muddled ingredients below the ice.

Step 3

Garnish with sliced strawberries, sliced grapefruit, and mint leaves. Serve immediately. Enjoy!
