This tart and fruity bourbon-based cocktail turns any time of day into happy hour.
In a double old-fashioned glass, combine 2 peach slices, 3 blackberries, mint, honey, and lemon juice. Mash gently with the back of a spoon until fruit releases juices. Add bourbon, remaining peach slices, and remaining blackberries. Fill glass with ice and top with seltzer.
