Red Grapefruit Water Ice

This idea came about by chance, as I left a grapefruit too close to the back of the fridge, and it partially froze. If you freeze a whole grapefruit, run it under hot water and cut the peel away, it can be sliced and eaten like sorbet - very refreshing. I've also just tried freezing segments of satsuma on a tray and then putting them into bags - works the same way, but much easier to eat! They would also be nice instead of ice cubes in a drink.
