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).
Angostura Bitters: Angostura bitters is a concentrated bitters (herbal alcoholic preparation) based on gentian, herbs, and spices, by House of Angostura in Trinidad and Tobago. It is typically used for flavouring beverages or, less often, food. The bitters were first produced in the town of Angostura (now Ciudad Bolívar, Venezuela), hence the name, but do not contain angostura bark. The bottle is recognisable by its distinctive oversized label. Angostura is Spanish for 'narrowing', the town of Angostura having been at the first narrowing of the Orinoco River.
