Watermelon Margarita – Monica Mixes

Ingredients

• 4 cups cubed watermelon, frozen! Make sure the watermelon is good and don't cut too close to the rind--we want the sweet stuff! Really freeze it!!!!
• 6 ounces good silver tequila I used Herradura
• 3 ounces Cointreau or any orange liqueur such as triple sec, Grand Marnier, dry Curaçao, etc.
• 4 ounces fresh lime juice
• to taste agave syrup or simple or demerara syrup...start with an ounce or two...wish I could be more precise but it depends on the sweetness of your watermelon--and your tastes
• saucerful kosher salt and/or Tajin I'll explain below....
