This is one of my mom's favorite drinks. We used to buy them and then take it home and try to deconstruct it at home and compare then side by side. It's still one of the great mysteries. When I went looking for her recipe it was right there in the card file under Beverage, the first recipe. She said use half a can (6 ounce) of orange juice concentrate. Remember those tiny 6 ounce cans? We're so super sized now no one would buy them I bet.
