Run a lime wedge around the rim of a margarita or coupe glass to wet the surface. Dip the rim into black salt on a small plate at a 45-degree angle and rotate to coat.

Fill a cocktail shaker or mixing jar two-thirds full with 1 cup of ice.

Measure 2 ounces of silver tequila with a jigger and pour into the shaker.

Measure 1 ounce of Cointreau or Triple Sec, then add to the shaker.

Measure 0.75 ounce fresh lime juice and 0.5 ounce fresh orange juice, then add both to the shaker.

Seal the shaker and shake vigorously for 10 to 12 seconds until the outside is frosted.

Place a cocktail strainer over the shaker opening and strain the margarita into the black-salt-rimmed glass, catching the ice.

Garnish with an orange slice and a lime wheel, then serve immediately while chilled.
