Easy apple crumble

We use demerara sugar in this classic apple crumble as it gives the topping a nice crunch, but you can use light brown or golden granulated sugar if that’s what you have. The apple juice is not essential, but ensures the filling is nice and juicy (and extra apple-y!).
Make sure your butter is cold from the fridge, to give a good texture. This is a generous crumble amount, for a nice thick layer. If you don’t use quite all of it, it can be frozen for later use. Or make a mini crumble
