Lychee fruit, though growing in popularity, isn't always easy to come by. This exotic fruit creates a delicious syrup to add to any cocktail and he floral sweetness is complemented by hints of rosemary and clove to cut through the bright flavor. Looking for a pro-level drink with none of the work? Mix this up with gin, ice, a little club soda, and garnish with a lime for the perfect sip to cool you down.
