A maraschino cherry (/mærəˈskiːnoʊ/ marr-ə-SKEE-noh or /mærəˈʃiːnoʊ/ marr-ə-SHEE-noh) is a preserved, sweetened cherry, typically made from light-colored sweet cherries such as the Royal Ann, Rainier, or Gold varieties. In their modern form, the cherries are first preserved in a brine solution usually containing sulfur dioxide and calcium chloride to bleach the fruit, then soaked in a suspension of food coloring (common red food dye, FD&C Red 40), sugar syrup, and other components.
Maraschino cherries are an ingredient in many cocktails, giving them the nickname "cocktail cherries." As a garnish, they often are used to decorate frozen yogurt, baked ham, cakes, pastry, parfaits, milkshakes, ice cream sundaes, and ice cream sodas. They are an integral part of an American pineapple upside-down cake. They are frequently included in canned fruit cocktail. They are also used as an accompaniment to sweet paan, and sometimes, along with some of the maraschino "juice," put into a glass of Coca-Cola to make an old-fashioned or homemade "Cherry Coke."
