Ready for your new go-to summer cocktail that's as pretty as the Iridescent Pitcher you make it in? Prickly pear syrup, one of our favorite (underused!) cocktail ingredients, is the star in this easy margarita recipe which is a little sweet, a little sour, a bit tangy (from the prickly pear) and overall goes down easy. Don't drink? We got you. We made a mocktail version too.
