black raspberry liqueur
fresh lime juice
simple syrup, optional
The "margarita mix" consists of two parts premium tequila, 1 1/2 ounces orange cognac, 1/2 ounce raspberry liqueur and a splash of fresh lime juice. Add simple syrup, if desired. Mix all of the "margarita mix" ingredients in a thin shaker with ice, a little diluted.
Get a good shake to get a good fizz. One-third of the glass is the "margarita mix" and the rest of the drink is champagne.
A wineglass should be chilled before you pour the drink. Cover the rim with raspberry sugar, but don't get any in the drink. To add fizz, drop a few raspberries in the drink.
