The cocktail that built the British Empire. This cocktail was introduced by the army of the British East India Company in India. In India and other tropical regions, malaria was a persistent problem. In the 1700s it was discovered that quinine derived from cinchona bark could be used to prevent the disease, although the bitter taste was unpleasant. To solve the problem British officers in India during early 19th century took to adding a mixture of water, and sugar to the quinine in order to make the drink more palatable; This is what we now know as tonic water. The next logical step was to combine the mixture with their daily gin ration, thus the g and t was born. To make this classic concoction pour gin with tonic over ice and garnish. A lime wedge is typically the garnish of choice, however some opt for lemon or even a cumber slice depending on the gin.
