Start by rimming your glass with salt. Run a lime wedge along the rim of a margarita glass, then dip the rim into a plate filled with coarse salt. This adds a nice salty contrast to the sweet and tangy drink.
In a blender, combine 2 oz of tequila, 1 oz of lime juice, 1 oz of orange liqueur, 1-2 tbsp of simple syrup, and 2 cups of ice. Blend on high until smooth and slushy. The ice should be fully crushed, and the drink should have a frosty, thick consistency.
Once blended, taste your margarita. If it’s too tart, add a little more simple syrup. If it’s not tangy enough, add more lime juice. The beauty of a frozen margarita is that you can tweak it to your liking.
Pour the blended margarita into your prepared glass. Garnish with a lime wedge on the rim of the glass for a burst of color and added flair.
Serve immediately while it's still frosty and refreshing. This drink is perfect on its own or paired with your favorite Mexican dishes, chips, and salsa.
