Sweet and sour mix is a mixer that is used in many cocktails and other drinks. It is a yellow-green colored syrup that is made from approximately equal parts lemon and/or lime juice and simple syrup. Simple syrup is made by combining equal parts water and sugar and cooking until the sugar is completely dissolved. Once the simple syrup is made, lemon and lime juice are added to it and the mixture is shaken vigorously with ice. The resulting mixture is a pearly-white liquid with a pronounced flavor. Sweet and sour mix is non-alcoholic, but it is used as an ingredient in many cocktails. It can also be used as a dipping sauce or glaze for food. Homemade sweet and sour mix can last for 2 to 3 weeks in the refrigerator. Some popular drinks that use sweet and sour mix include margaritas, amaretto sours, and Long Island iced teas.
