This is my concoction for when the day gets too hot and the air-cond decides to go on the blitz (yes, can you believe it?!)
Mix 1 part Ribena, 3 parts 7-Up and 1 part water. Add a million ice-cubes and slices of grapes. You can substitute with any fruits, but I am loving grapes at the moment.
End result: a refreshing, tart thirst-quencher!
