When visiting Naples, a friend introduced us to the classic French 75 cocktail. This was originally created at the New York Bar in Paris, later Harry’s New York Bar, in 1915. The potent combination of gin, lemon juice, Champagne, and sugar was said to have a kick like a French 75mm field gun and the name stuck.
There are many recipes around which try and give this classic cocktail an Italian twist. One adds limoncello instead of the lemon juice; another muddles the gin with basil, before using grapefruit juice and bitters. One recipe substitutes grappa for gin.
But I think this recipe via Feast best preserves the gin/fruit/fizz intent of the original. It uses the freshly squeezed, slightly bitter, juice from a blood orange, a fruit native to Italy and the primary orange grown in the country. And of course Prosecco instead of Champagne.
