Don’t fear: This crimson cocktail gets its bite from bold blanco tequila, not venom. Agave nectar and muddled blackberries soften that bite with a hint of sweetness, and give the Black Widow its signature spooky hue. Don’t forget the fresh basil and blackberry garnish for the full effect. Its bite brings pleasure, not pain.
In a shaker, muddle the blackberries and basil.
Add the remaining ingredients and fill with ice.
Shake well and strain into a stemless Martini glass filled with fresh ice.
Garnish with a blackberry and basil leaf on a toothpick.
