Try boiling canned peaches with a cup of water including the juices included in the can, some sugar to your liking until they are tender ( about an hour) . Once done add 1/4 tsp of unflavored gelatine. Puree everything in a blender and viola.
You can also do the above and mix it with the scratch pastry cream recipe here on CC and you have a peach custard. Taste delicious.
