Prep two drink glasses with a salted rim by rubbing a lime wedge around the rim of the glass, then dipping in kosher salt. Fill glasses with ice. If desired, chill the prepped drink glasses in the freezer until margaritas are ready to pour.
Add all ingredients into a large cocktail shaker with a little bit of ice and shake vigorously for about 15-20 seconds. Strain margaritas into prepped glasses. Garnish with pomegranate seeds, a lime wheel or wedge, and a mint leaf if desired.
