This is a pretty twist on the classic drink. Since blood oranges are in season, I have been juicing them and freezing the juice to use in future recipes, but I couldn't resist using some to make us a tasty beverage to go with our taco salad the other night (recipe below).
1 C fresh squeezed blood orange juice
1/2 C fresh squeezed lime juice
1/2 C tequila
Simple syrup, to taste (1 part water, two parts sugar simmered until dissolved and cooled)
Combine all ingredients in a cocktail shaker and serve over ice.
