Build in a Collins glass over fresh ice. Add tequila, lime, and crème de cassis. Top with ginger beer. Stir gently. Garnish with a lime wedge. The cassis sinks to the bottom — that's the visual signature.
Trader Vic, 1946. The "Devil" — for the deep red cassis at the bottom of the glass.
Collins glass, fresh ice, cassis visible at the bottom. Tell guests to stir before sipping or sip through the layers.
Spicy, fruity, refreshing. The cassis is the surprise — most guests don't expect blackcurrant in a tequila drink.
