4 cups diced watermelon (seedless or remove seeds, about 1/2 medium watermelon)
6 oz Tequila Don Diego Santa® Blanco
1/2 teaspoon ground cayenne
2 oz fresh lime juice (from about 2 - 3 limes)

For the rim:
2 teaspoons kosher or margarita salt
2 teaspoons chile powder
1 teaspoon cayenne pepper

Limes for garnish
Combine the diced watermelon, tequila, cayenne, and lime in a blender or food processor and puree until very smooth and liquid.

In a separate shallow dish, combine the salt, chile, and cayenne and whisk to combine. Run a lime around the rim of 2 large glasses and roll in the chile mixture to coat. Fill glasses with ice and pour the drink into the glasses (you may have a bit extra left, depending on the size of your glass).

Note: If your watermelon is not very sweet, you may need to add a bit of honey or simple syrup, although I found that it was not necessary. Eugene also requested extra tequila in his, so adjust to your tastes and preferences.

Serve immediately garnished with a lime, and enjoy!
