Pour IPA into a chilled cocktail, coupe, or double rocks glass. Combine Aperol, gin, lemon juice and egg white in a shaker and shake briefly just to combine, then add a handful of ice and shake vigorously for a minute or so. Strain into your glass, garnish, serve immediately.
De-stem and pit cherries. Place them in a chaker. Combine with the simple syrup and muddle until the cherries are thoroughly crushed. Add the lemon juice, Aperol, and bourbon. Fill your shaker with ice and shake for 10 seconds. Strain into a tall glass over new ice and top with sparkling water. Add a straw and sprig of fresh mint.
