Mixing cocktails is a pure magic. When seemingly incompatible ingredients are mixed together in a glass, and the result is gorgeous, it can’t be called otherwise as ‘magic’.
The etymology of the word ‘cocktchail’ is very ambiguous. More than a dozen of different versions explains its origin.
If you look in the Oxford Dictionary, the first mention of the word ‘cocktail’ dates back to 1803 in the United States. People called mixed drinks that way.
