Enjoy this keto margarita without feeling guilty! This recipe uses Swerve instead of sugar and orange-flavored sparkling water to mimic the taste of orange liqueur. This recipe was developed at its original yield. Ingredient amounts are automatically adjusted, but cooking times and steps remain unchanged. Note that not all recipes scale perfectly. 1. Fill a shaker half-full with ice. Add tequila, lime juice, and sweetener to the shaker. Seal and shake vigorously until outside is frosted, 10 to 15 seconds. 2. Place salt on a plate. Run 1 lime wedge along the rim of the Mason jar. Press the rim down into salt. Fill the jar with ice cubes. 3. Strain margarita into the jar. Top with sparkling water
