Buck's Fizz

Buck’s Fizz is an English cocktail made with a combination of champagne and orange juice, where the ratio should be 2:1, unlike the Mimosa, which is typically made with equal parts champagne and orange juice. The cocktail is served neat and undiluted in a champagne flute, and it can be garnished with an orange twist.

It was invented in the 1920s by Malachy McGarry at Buck’s Club in London, hence the name. Nowadays, Buck’s Fizz is especially popular at weddings, and it is sometimes used as a hangover cure.
