A margarita is a cocktail made with tequila, orange liqueur, and lime juice. The classic recipe uses a 2:1:1 ratio of tequila, orange liqueur, and lime juice. The orange liqueur can be Cointreau, Grand Marnier, or Triple Sec. Some recipes suggest adding a sweetener like agave nectar or simple syrup to taste. The drink can be served on the rocks or blended with ice to make a frozen margarita. A salted rim is optional and can be achieved by rubbing a lime wedge around the rim of the glass and dipping it in kosher salt. The best tequila to use for margaritas is a matter of personal preference, but reposado tequila is typically the go-to. Freshly squeezed lime juice is recommended for the best flavor.
