Watermelon Margarita

(about 2 servings)

*This recipe doesn't make a very strong drink. I'm a lightweight; if I'm not careful I'll embarrass myself before collapsing somewhere after just 2 or 3 of these. If you prefer something stronger, then reduce the amount of watermelon to 1 cup, and increase the alcohol. :)

*1 1/2 cups cold seedless watermelon, cubed
2 1/2 oz tequila
1/2 oz cointreau, or an orange liqueur
1/2 oz midori, or a melon liqueur
juice from 1 small key lime
4 ice cubes

Place everything into a blender, and process until smooth. Serve immediately.
