There are multiple ways to make a Tequila Sunrise Margarita. This recipe is for the visually impressive frozen version. There is also a video tutorial for a non-frozen version (view that here), which is very similar to the original Tequila Sunrise.
You will find some recipes for the blended version that call for including the grenadine in the blender. That makes for a great-tasting frozen margarita, though you lose the visual 'sunrise' effect. The recipe below keeps it separate, adding the grenadine to the glass and pouring the blended mix on top. You can stir it up a little bit to bring up some of the sweetness and as the drink melts, the two flavors mix perfectly. You can also very easily transform this cocktail into a frozen ice pop for the hot summer months!
