Instructions

  1. Stir the allulose into the warm water until dissolved, then add the orange zest and let it steep while you prepare the glass.

  2. Run the lime wedge around the rim of a rocks glass and dip the rim in coarse salt. Fill the glass with ice.

  3. Put the tequila, lime juice and orange syrup in a cocktail shaker with a handful of ice. Shake hard for 15 seconds, until the shaker is frosty.

  4. Strain into the glass over the fresh ice and garnish with a lime wheel.

Tips for success

  • Triple sec and other orange liqueurs are mostly sugar. A little fresh orange zest gives the same orange aroma for almost no carbs, and a drop of pure orange extract works too.
  • For a pitcher (8 drinks), combine 2 cups tequila, 1 cup lime juice, ½ cup allulose dissolved in ½ cup warm water and the zest of 1 orange. Chill, then shake or stir with ice to order.
  • Alcohol can hit harder and faster on keto, so pace yourself and drink water between rounds.

Nice to have, not needed

  • A cocktail shaker chills and dilutes it just right — a jar with a tight lid works.
