Back in the 1950s when A-bombs were being tested in Nevada, an unknown bartender in Las Vagas came up with a little drink called the Atomic Cocktail. With Vodka, Cognac, Amontillado Sherry & topped with Brut Champagne, all we can say is this is a drink to handle with care.
Shake first three ingredients with ice and fine strain into a chilled glass. Then top with Champagne.
