How to Make It
Combine peeled and sliced peaches, fresh lemon juice, water, honey, and, if desired, refrigerated lemongrass paste in a blender. Process until smooth, about 1 minute. Pour peach mixture evenly into 4 highball glasses filled with ice. Add 1 oz. bourbon to each, and top each with 1/4 cup club soda. Gently stir until combined. Garnish with fresh Thai basil or sweet basil sprigs.
