Combine 0.5 cup fresh lemon juice, 0.5 cup fresh lime juice and 0.75 cup simple syrup in a jar. Stir or shake until fully mixed. Chill in refrigerator up to 1 week. Use 0.75 oz of this mix per margarita.

Prepare Glass

Run a lime wedge around the rim of a rocks glass. Spread the coarse salt on a small plate and dip the wet rim into the salt to coat. Fill the glass with large ice cubes and set aside.

Build & Shake

In a cocktail shaker filled halfway with ice, add 2 oz Dobel Diamante Cristalino tequila, 1 oz Cointreau, 0.75 oz homemade sour mix, 0.5 oz fresh lime juice and 0.25 oz simple syrup if you prefer slightly sweeter balance.

Shake vigorously for 10–12 seconds until the shaker is well chilled and slightly frosted.

Finish & Serve

Double-strain the mixture over the prepared rocks glass filled with fresh ice (to avoid over-dilution from the shaker ice).

Squeeze a fresh lime wedge over the cocktail to add a bright burst of citrus, drop the wedge into the glass as garnish.

Serve immediately with a short straw or stirrer. Optional: provide an extra lime wedge on the side.
