Instructions

1. Preheat the oven to 180°C.
2. Peel and core the apples, then chop roughly into bite-sized chunks.
3. Put the fruits, water and half of the sugar in a saucepan. Bring to the boil and cook for 5 minutes until tender.
4. Transfer to an oven-proof dish.
5. Rub the margarine/butter with the flour and cinnamon until you get fine breadcrumb-like crumbles, then add the oats and the leftover sugar.
6. Cover evenly the fruit mixture with the crumble, slightly pressing the top with a spoon.
7. Bake for 20-25 minutes until golden and crispy.
8. Serve it warm with vanilla ice-cream, custard or Greek yoghurt.
