Traditionally, Campari is designed as an aperitif, so you’re meant to sip it slowly before eating a meal — its bitterness and medicinal ingredients help invigorate the digestive system. However, one of the most popular uses of Campari is within a Negroni cocktail (just mix one ounce of gin, one ounce of vermouth, and one ounce of Campari before serving over ice and garnished with an orange peel). Campari is a complex, bittersweet liqueur, so you’ll want to be mindful of how you pair it with other cocktail ingredients; too much can be super overwhelming on the palette.
