Wwlcome back to 3-Ingredient Happy Hour, the weekly drink column featuring super simple yet delicious libations. This week we’re making a classic — I’m talking 1930s —cocktail: the Brainstorm.
The Brainstorm gets its boozy backbone from plenty of Irish whiskey, which is balanced by herbaceous Bénédictine and dry vermouth. Though you’re probably used to using sweet vermouth in whiskey-based, Manhattan-ish beverages, here you’re already getting plenty of sweetness from the liqueur, so it’s best to go with the driest vermouth you can find. To make this potent potable, you will need:
60ml Irish whiskey
15ml dry vermouth
Combine everything in a stirring glass filled with ice and stir until the glass is too cold to hold comfortably. Do not be afraid of dilution with this baby. Strain into a coupe, garnish with a strip of orange zest if you’re not afraid of the extra ingredient, and let your mind be soothed by the storm.
