You’d never guess it by looking at the ingredients, but this Mexican cocktail hails from tiki visionary Trader Vic’s Pacific Island Cookbook, published in 1968. Interestingly, there is a chapter on Mexico along with a few tequila based cocktails.
The drink is really a Black Russian with tequila and a twist. The tequila gives it a richer and sweeter flavor and depth that overcomes the strong coffee flavor. Plus, the lemon twist adds a kind of espresso character to the endeavor. Makes sure you express the oils onto the surface of the drink.
I think this works better than the usual mix of vodka and Kahlua.
1.5oz blanco tequila
1oz coffee liqueur
Garnish: lemon twist
Pour into ice-filled old-fashioned glass and stir. Add lemon twist.
