In a cocktail shaker, muddle the kiwi slices, strawberries, and mint leaves until the fruit is well mashed and the mint releases its aroma.

Add the bourbon, simple syrup, and fresh lemon juice to the shaker.

Fill the shaker halfway with crushed ice, then shake vigorously for about 10-15 seconds until everything is well combined and chilled.

Strain the mixture into a glass filled with more crushed ice.

Top with soda water if you want a lighter, fizzier version, or enjoy it as is for a stronger flavor.

Garnish with a sprig of mint and a slice of kiwi or strawberry for that extra pop of color and flavor.
