In a shaker, combine 1½–2 oz tequila, lime juice, ½ oz orange liqueur, and ½ oz simple or agave syrup.
Add ice to the shaker, cover, and shake for about 15 seconds until cold and frothy.
Rub a lime wedge on the rim of your glass and dip it in coarse salt. Set aside.
Strain the margarita into the prepared glass and garnish with a lime wedge. Enjoy your homemade version Longhorn Steakhouse The Perfect Margarita Recipe.
