I have three Bramley apple trees in my garden and in the autumn I pick cook and freeze apples, some sliced, some diced and some pureed. Throughout the year I can then make apple cakes, pies and crumbles.
One of my favourite things I like to make is cider apple curd which is delicious spread on toast, folded into yoghurt as a pudding or into custard to make a fruit fool. This may seem a long recipe but if you make the apple curd in advance and have some defrosted apple puree it is mainly the baking of the cake and the assembly time that is needed.
