This is optional, if you do not want to put gelatin on top leave this last step out! Soak the gelatin sheets for 5 minutes in cold water, then take them out, squeeze ut the water from them. Put water, peach liquid from can and gelatin in a saucepan and heat up gently until the gelatin has dissolved. Let it cool a little bit and keep stirring, then pour it over the sliced peaches so they are covered. Then put in the fridge for about 30-60 minutes until it has set. It is then ready to be served!
