Mix kosher salt and sugar on a plate. Rub an orange wedge on the rim of the glass, then dip them in the sugar/salt mix. Fill the glass with ice and set aside.

In a shaker with ice, combine tequila, lime juice, orange juice, and orange liqueur. Shake until cold.

Pour the mixture into the prepared glass.

Drizzle grenadine along the inside edge of the glasses so it sinks, and lightly stir at the bottom.

Garnish with an orange wedge and drizzle a little more grenadine on top.

Enjoy!
