This simple, tangy apple sauce takes no time to make and freezes brilliantly. Fantastic with roast pork, but also great on pancakes or latkes.
Put the apples in a saucepan with the lemon zest and water. Cover and cook over a low heat until they are soft and mushy.
Take off the heat and beat in the butter and the sugar. Cool.
Use Bramley apples that will cook down to a fluffy sauce and taste as you go to get the right balance of sweet and tartness.
