Comforting Classic Apple Crumble vs Classic Apple Crumble with Oat Topping

Both crumbles bake apples beneath a topping of flour rubbed with cold butter, then stirred with oats and sugar, but they lean in different directions. The first brightens its filling with lemon juice and warms it with nutmeg alongside cinnamon, keeping the spice in the fruit, and is served with double cream on the side. The second piles in a full kilo of chunked apples seasoned only with cinnamon and sugar, and builds a richer, more buttery topping in which light brown sugar and oats add extra crunch and a caramel note.
