Ingredients

1/2 cup sugar 

1/2 cup water 

3 wide strips orange zest 

12 ounces watermelon cubes (about 2 cups) 

1/4 cup fresh lime juice 

3/4 cup white or silver tequila 

Lime wedges 

Preparation

In a small saucepan, bring sugar, water, and orange zest to a boil over high. Reduce to a simmer and cook until sugar dissolves, 3 minutes. Let syrup cool in a bowl. In a blender, puree watermelon cubes until smooth. Strain through a fine-mesh sieve, pressing on solids, into a pitcher (you should have about 1 cup juice). Stir in syrup, lime juice, and tequila. Fill salt-rimmed glasses with ice, then pour margarita mixture over top. Garnish with lime wedges.
