Put fruit into saucepan with sugar and a bit of lemon juice to stop it browning. Add half cup water to cover the base of the saucepan. Cover the saucepan, bring to boil, then turn it down to a simmer. Stew the apples until soft but not pureed, unless that's the texture you prefer. Take care not to steam off all the water. If mix is too liquidy, drain a little.
