Crumble is a wonderful thing! It is incredibly simple, takes barely any time and yet tastes amazing. It is the sort of pudding that is ideal for an evening where you know you have lots to do, but everyone still wants to have a nice, warming pudding. I wasn't really sure how to best do this section, because I enjoy cooking crumble with all kinds of fruits and moreover have two different ways of doing the topping, so it is all rather complicated. The first is simpler and less time-consuming, but not as crisp on the top. The second has an almost shortbread-like topping.
