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.
Falernum: Falernum is either an 11% ABV syrup liqueur or a nonalcoholic syrup from the Caribbean. It is best known for its use in tropical drinks. It contains flavors of ginger, lime, and almond, and frequently cloves or allspice. It may be thought of as a spicier version of orgeat syrup. The form can be alcoholic (syrup liqueur) or nonalcoholic (syrup). Versions with alcohol are generally lower in proof (≅15 ABV), adding rum and emphasizing the clove, ginger, or allspice flavoring aspects for use in mixing cocktails, typically tropical or tiki drinks. It is also enjoyed on the rocks. Depending on sugar content, the consistency is often thick and is therefore sometimes referred to as "velvet falernum" because of the feeling it leaves on one's tongue. Brands vary and the color can be white to light amber, and it may be clear or translucent.
