In a shaker, muddle the strawberries and kiwi slices. This means pressing them with a muddler or the back of a spoon to release their juices and flavors.

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

Fill the shaker with ice, covering the liquid and fruit.

Secure the lid on the shaker and shake vigorously for about 15 seconds. The goal is to chill the mixture thoroughly and mix all the ingredients well.

Strain the mixture into a glass filled with fresh ice to catch any fruit pieces and seeds.

If you like a lighter drink, top it off with a splash of soda water.

Garnish with a sprig of mint and maybe a slice of kiwi or strawberry on the rim of the glass.

Serve immediately and enjoy your Kiwi & Strawberry Bourbon Smash!
