The Ritz Fizz was created as the Ritz-Carlton hotel chain's signature cocktail in 1934 upon the repealing of prohibition in the United States. It was first concocted in the bar at The Ritz-Carlton Hotel in Boston, Massachusetts. Versions Ritz Fizz (Boston Ritz Fizz) In a Champagne Flute glass mix: 1/2 oz. (12.5 mL) Disaronno Amaretto 1/2 oz. (12.5 mL) De Kuyper Blue Curacao 1/2 oz. (12.5 mL) fresh lemon or lime Juice Top off with Champagne. Stir together. Garnish with a rose petal. Variants Some recipes use Sour mix or Sweet & Sour mix instead of the lime or lemon juice. Le Ritz Fizz (Canadian Ritz Fizz) The Ritz-Carlton Hotel in Montreal makes their version with 1/2 oz. (12.5 mL) of apple liqueur instead of the Amaretto and Blue Curaçao and garnishes it with a sugar cube dipped in raspberry liqueur. This is probably due to copyright infringement since the Montreal Ritz-Carlton is privately owned and has not been part of the Ritz-Carlton group since the 1970s, which was when the hotelier pulled out of Montreal due to the city's economic decline.
