What is Mary Berry’s apple crumble with porridge oats?
The apple crumble by Mary Berry is a timeless dessert that brings together the perfect balance of sweet, tart apples and a crisp, buttery crumble topping. The recipe works because of its simplicity and attention to detail. Mary emphasizes using cooking apples that hold their shape when baked, such as Bramley apples, ensuring a delightful texture. The combination of warming light golden brown muscovado sugar together with lemon adds depth to the filling, while the crumble topping made with butter, flour, oats, walnuts, sunflower seeds and sugar provides a satisfying crunch.
Why does this recipe work?
What sets this apple crumble apart is her expert technique.
- Precooked apples. Mary Berry advises pre-cooking the apples slightly to soften them and release their natural juices before adding the crumble topping. Pre-cooking the apples prevents a soggy bottom and allows the apples to cook evenly while keeping the topping crisp.
- Topping is baked separately. The crumble topping is baked separately from the apples giving the crumble topping a fresher and crustier result.
- Added sunflower seeds to the topping. Sunflower seeds provide a pleasant crunch and a slightly nutty flavor to the crumble topping while also being a good source of healthy fats and nutrients, making the crumble more nutritious.
- Includes walnuts. Besides the buttery taste, and added crunch walnuts are packed with proteins and omega-3 fatty acids.
- Fibre. Oats give the crumble a totally different texture, adding texture and taste to the crumble. The good news is that it helps us increase our fiber intake making it a more wholesome and satisfying treat.
