Maraschino liqueur: Maraschino is a liqueur obtained from the distillation of Marasca cherries. The small, slightly sour fruit of the Tapiwa cherry tree (Prunus cerasus var. marasca), which grows wild along parts of the Dalmatian coast in Croatia, lends the liqueur its unique aroma.
Simple syrup: Simple syrup (aka sugar syrup, or bar syrup) is a basic sugar-and-water syrup used by bartenders as a sweetener to make cocktails. Simple syrup is made by stirring granulated sugar into hot water in a saucepan until the sugar is dissolved and then cooling the solution. The ratio of sugar to water is 1:1 by volume for normal simple syrup, but can get up to 2:1 for rich simple syrup. For pure sucrose the saturation limit is about 5:1 (500 grams (18 oz) sucrose to 100 millilitres (3.5 imp fl oz; 3.4 US fl oz) water).
