All sorts of water fruit ices can be made by mixing half a pint of juice, such as currant-juice, with twice that quantity of syrup, and freezing. Grated ripe pine-apple, pounded and bruised, ripe cherries and greengages, strawberry-juice, raspberry-juice, can be mixed with syrup and frozen. Sometimes a little lemon-juice can be added with advantage, and in the case of cherry ice and greengage ice a little noyeau added is an improvement.
