A few variations on a super-simple cocktail will please friends who like sweet drinks and friends who don't.
My sister says a good cook is one who can whip up dinner out of whatever is in the cupboards — and she doesn't mean a can of Campbell's. Recently stuck with a cocktail craving, only a few ingredients in the house, and no energy to go out and buy stuff, I tried to make my sister proud. At my disposal: a little wedge of watermelon and a bottle of Sauza gold tequila.
I chopped up the watermelon and stuck it in the blender.
