Sour mix is a mixer used in many cocktails, notably the Long Island Iced Tea family. It is made from approximately equal parts lemon and/or lime juice and simple syrup and shaken vigorously with ice. This produces a pearly-white liquid with a pronounced flavour. Egg white may be added as a foaming agent, to improve the texture of the finished product. Pre-mixed versions are available, and are in use in many bars - these typically consist of a powder which must be rehydrated by adding water prior to use.
One of the earliest known printed references to the word "cocktail" described a drink made from "Spirit of any kind, sugar, water and bitters". This is very similar to the drink that would these days be known as sours - a spirit or liqueur, shaken vigorously with ice, lemon juice and sugar.
- One cup of sugar
- One egg white
- Two cups of water
- Two cups of lemon juice, preferably freshly squeezed
Alternately, try this "vegan" recipe:
- 2 parts lime juice
- 2 parts simple syrup (sugar water)
- 1 part orange juice
- 1 part lemon juice
- Whisk egg white (unless preparing vegan version) in a medium-sized bowl until frothy
- Stir in the sugar and water or simple syrup
- Add the lemon juice (and lime and orange juices if using)
- Stir all ingredients well
Store the mix refrigerated and use within three days of making it.
