Melt the jellies in the water and juice. Stir in the ice cream quickly and, if the mixture sets at this stage, place the bowl over a pan of hot water and stir until liquid again. Add lemon juice as required as this mixture will be very sweet. Stir in the milk, and pour into a prepared mould. Turn out when set.
Pineapple Cream: Substitute pineapple jelly and juice for orange.
