¼ cup fresh American blueberries
1 oz fresh strong coffee, chilled
juice of ½ lemon
½ oz simple syrup
1 oz tequila
⅓ oz triple sec

Start off by dropping the blueberries into the bottom of a cocktail shaker. Smash them up really well with a muddler. Add the tequila and triple sec. Squeeze in the lemon juice, add the simple syrup, and pour in the coffee. Shake well with ice.

Now strain it out into a chilled martini glass. Don’t fine strain it, or you'll lose a lot of that blueberry pulp, which adds texture and acts as a garnish for the drink.

We’re staying up all night now!
