Storing / Making ahead of time options

Crumbles are best when you enjoy them fresh and warm from the oven. But they can be stored in an air-tight container in a cool dark cupboard for a few days and then reheated in the microwave.

Crumble topping can be frozen in a freezer-safe bag or container and so can the fruit. If you freeze both parts separately you can make up the crumble when you’re ready. It can be baked from frozen, just don’t forget to adjust the cooking time slightly.

You can use either Bramley apples or eating apples. Bramley apples benefit from being cooked in a saucepan to break them down and sweeten them before they bake. Eating apples don’t need this and will soften in the oven.
Best served with custard or ice cream.
Keeps very well in the fridge for up 2 days.
Make the crumble topping ahead of time and store it in the freezer and bake from frozen. (It will still be malleable).
