One packet of orange jelly, one packet of lemon or lime jelly, or whatever flavour you prefer. I chose lime for the color, one can of evaporated milk, ice.
Prepare the lime or lemon jelly according to the packet, the day before. Pour in a square tin and keep in the fridge overnight. The next day, cut the jelly into squares and leave in the fridge whilst you prepare the rest. Mix the orange jelly with half of the water , make sure its dissolved then add the evaporated milk and the ice, making sure that the ice melts. Put a little water in a tin, or jelly mould and get rid of the excess, pour in the mixture and quickly scatter the lemon jelly squares all over, so it has a mosaic effect when set. Keep in the fridge for 3 or 4 hours to set.
