In a cocktail shaker filled with ice, combine the Aperol, mezcal, and vermouth. Add 4-6 drops of Orange Cream Citrate. Stir until well-chilled and strain into a glass with one large ice cube.
The original name of this drink was listed on Bittermen's website as Death and Glory. As there was already a drink here (a different drink) with that name, I translated to Spanish as a nod to the Mezcal.
