1 tablespoon kosher salt
1 1/2 fluid ounces tequila
1 fluid ounce orange flavored liqueur (such as Cointreau®)
1/2 fluid ounce lime juice
1 cup ice
1 lime wheel
Sprinkle salt on a small plate. Lightly wet the rim of a cocktail glass or margarita glass with a damp paper towel. Dip the moistened rim in salt to coat. Set aside.
Combine tequila, orange-flavored brandy, and lime juice in a cocktail shaker. Add ice and shake until chilled. Strain into a salt-rimmed cocktail glass or a salt-rimmed, ice-filled margarita glass.
Garnish with a lime wheel.
