Between The Sheets
1 ounce brandy
1 ounce light rum
1 ounce Cointreau
1/2 ounce lemon juice
Garnish: Lemon twist.
Shake with ice. Strain into a cocktail glass.

Not many (proper) cocktails contain more than one base spirit. Since Cointreau is a full-proof product, it can almost be considered a third base spirit in this one!
