Apple brown betty
Preheat the oven to 180°C/350°F/Gas mark 4. Lightly grease a 1.2-litre/2pt ovenproof dish.
Cook the apples with 15g/1⁄2oz of the butter, 15g/1⁄2oz of the sugar, the lemon zest, cinnamon and nutmeg for 10–15 minutes until the apples are soft enough to beat to a purée.
Melt the remaining butter in a frying pan over a low heat, and add the breadcrumbs and remaining sugar. Toss until the crumbs are coated, and continue tossing while you fry the crumbs until they are golden brown.
Spread one-third of the crumbs in the greased ovenproof dish, and add half of the apple purée in an even layer. Add another third of the crumbs and the remaining apple, then finish with a layer of crumbs. Bake in the oven for 20 minutes or until crisp and golden on top. Serve hot, either plain or with cream or ice cream.
