We all know how cooling the classic combination of lime and mint is on a warm day. But rhubarb? While this sour vegetable is typically reserved for pies and crumbles, we capture its unique flavor in a refreshing springtime cocktail.

This one is easy to make non-alcoholic, too. Simply omit the rum and add an extra splash of soda. It doesn't take a lot of ingredients, it's simple to make, and leftover rhubarb syrup can be added to all your favorite drinks.
