Rub the lime wedge around the rim of a chilled rocks or margarita glass. Spread the kosher salt or Tajín on a small plate, then gently press and twist the glass rim into the salt to coat evenly. Set the glass aside.

Juice citrus

If not already done, juice fresh blood orange(s) until you have 1.5 oz (about 1 small blood orange) and juice a lime to yield 0.75 oz. Strain if you prefer a smoother cocktail.

Mixing

Add 2 oz blanco tequila, 1 oz orange liqueur, 1.5 oz fresh blood orange juice, 0.75 oz fresh lime juice, and 1 oz sour mix into a cocktail shaker.

If you like a slightly sweeter drink, add 0.25 oz simple syrup to the shaker.

Fill the shaker with ice (about 1 cup) to near the top, secure the lid, and shake vigorously for 10–15 seconds until the outside of the shaker is frosty and well chilled.

Serve

Strain the cocktail into the prepared glass over fresh ice (or serve neat in the chilled glass if you prefer).

Garnish with a blood orange wheel on the rim and serve immediately.
