Your new favorite martini is actually a margarita.
Ingredients
2 teaspoons Diamond Crystal kosher salt or Tajín Clásico seasoning
1 medium lime
1/2 medium orange
2 ounces reposado or blanco tequila
1 ounce orange liqueur, preferably Cointreau
1/2 ounce olive brine, plus more as needed
Ice
Olives, for garnish
Instructions
Spread 2 teaspoons Diamond Crystal kosher salt or Tajín in an even layer on a small flat plate. Halve 1 medium lime. Cut 1 lime wedge from one half. Run the lime wedge over the rim of a martini glass to moisten, then set aside for garnish. Invert the glass onto the plate, turning it as needed, to coat the rim. Place the glass in the refrigerator or freezer for at least 5 minutes.
Juice the remaining lime pieces until you have 1 ounce, then pour into a cocktail shaker. Juice 1/2 medium orange until you have 3/4 ounce and add to the shaker. Add 2 ounces reposado or blanco tequila, 1 ounce orange liqueur, and 1/2 ounce olive brine. Fill the shaker halfway with ice, seal, and shake until the outside of the shaker is very frosty, about 20 seconds. Taste and add more olive brine if desired.
Pour through a strainer into the glass. Garnish with the reserved lime wedge and olives onto a toothpick.
