Calamansi Rickey Cocktail
This quick and easy cocktail showcases the refreshing zing of calamansi, aka calamondin or Philippine lime. The citrus fruit, a staple of Filipino and Southeast Asian cooking, tastes like a very tart combination of lemon, lime and orange. This recipe makes enough syrup for 4 cocktails and the syrup can be made ahead. For a nonalcoholic version, simply leave out the gin.
To make ahead: Refrigerate syrup (Step 1) for up to 1 week.
