You know what are delicious? Blood orange margaritas, that's what. A couple of years ago, I whipped up some sour mix and made cousin Ken a margarita, and he hasn't been able to get it out of his head. We've had our beach trip with Ken and his wife Candace on the books for months and months. We didn't have much of a plan, but there was one thing that was certain. Ken expected margaritas. I had fully intended to make some sour mix, but then I realized that deconstructed sour mix--or rather, simple syrup and some lemons and limes--would be more flexible. Especially because I had blood oranges on my mind. I love a good margarita. Bring it on!
