Tonic water

Tonic water is a carbonated soft drink with a distinctive bitter flavor derived from quinine, which is extracted from the bark of the cinchona tree. Originally used as a malaria preventative in tropical regions, it has become a beloved staple of bar culture. It is best known as the mixer in the classic gin and tonic cocktail. In the kitchen, tonic water is used not only as a drink but also as an ingredient in frying batters, the carbon dioxide it contains gives fried foods a lighter, crispier texture. It also works well in marinades or as a base for fruity cocktails with vodka or rum.
