Virgin frozen margarita recipe. We have a core group of 12 bloggers, but we will always need substitutes and if there is enough interest would consider additional groups. Dip the rim evenly into the water and then into the salt. Dip rim into salt. Rub the edge of 4 glasses with the lime wedge, then dip the rims in the coarse sugar. Yield 10 oz. Combine the frozen limeade concentrate, orange juice, grapefruit juice and ice cubes in a blender and blend until slushy. We are sorry. We had both drinkers and non drinkers and even the drinkers thought these margaritas were awesome. They will not taste exactly the same, but something similar can be achieved. One of my daughters has been home from college with me for most of the summer. We are sorry. Cracking open the coconut was really the most confusing part.
