Ingredients

For the Fruit Layer

  • 800 g Apples mix of cooking and eating apples (see notes)
  • 300 g Blueberries fresh or frozen
  • tablespoons Cornflour (cornstarch)
  • 60 g White sugar caster or granulated
  • ½ teaspoon Ground cinnamon
  • ½ teaspoon Ground ginger
  • ¼ teaspoon Ground nutmeg

For the Crumble Topping

  • 125 g Butter
  • 150 g Plain flour (all-purpose flour)
  • 60 g White sugar caster or granulated
  • ¼ teaspoon Salt
  • 60 g Oats
  • 45 g Demerara sugar

Instructions

Make the crumble topping

  • Preheat the oven to 180C/ 350F/ GM 4
  • Put the flour, caster sugar and salt into a mixing bowl and stir briefly.
  • Cube the butter, add to the bowl and rub it into the flour until the mixture resembles breadcrumbs.
  • Mix in the oats and demerara sugar.

Prepare the fruit

  • Mix the cornflour, sugar and spices together in a small bowl.
  • Peel and core the apples then chop roughly.
  • Place the apple chunks in a large mixing bowl and mix them up (this is very important if using a variety of apples).
  • Add the blueberries and the sugar mixture and stir well.

Assemble and bake

  • Lightly grease a large baking dish with butter.
  • Tip the fruit into the dish, scattering any leftover sugar & cornflour mixture over the top.
  • Spoon the crumble topping over the fruit, ensuring it is all covered.
  • Place on a baking sheet (to catch any drips if the fruit bubbles over the edge) and bake in a preheated oven for 40 minutes until the top is golden.
  • Let stand for 15 minutes then serve.

Notes

  • Measure ingredients accurately – using digital scales along with gram measurements is much more precise than using cup measurements.
  • Use a large, deep-sided oven-proof bowl to cook the crumble in.
  • Ensure all apple skins, cores and pips are removed – if left on when the apples are chopped they will be unpleasant to chew.
  • Don’t forget the cornflour – this is needed to turn the liquid from the fruit into a scrumptious sauce around the fruit. If left out there will be a thin, unappetising liquid in the base of the dish.
  • The spices are optional. You can make a straight blueberry and apple crumble without them if desired.
  • Make vegan blueberry crumble by replacing the butter with vegan block butter and adding in an extra ¼ teaspoon of salt to the crumble topping.
  • Or make gluten-free apple and blueberry crumble by using gluten-free plain flour. There is no need to replace the cornflour as this is naturally gluten-free. However, take care with the oats since although they are technically gluten-free, oats are often processed in factories also handling gluten-based products, so cross-contamination can occur. If in doubt, leave the oats out of the recipe.
 
The best apples to use
Opinions on this subject are very individual. Some people will swear by using only cooking apples and others will rave about using just eating apples:
  • Cooking apples break down into a sauce when cooked. They are also relatively tart so require plenty of sugar to sweeten them.
  • Eating apples, on the other hand, hold their shape when cooked and are typically sweet enough to eat without the addition of too much extra sugar.
What type of eating apple to use is, again, down to personal preferences:
  • Opt for Granny Smiths if you like your crumble with plenty of sharp tanginess to it.
  • Pink Lady apples are a good bet if you’re not so into sharp fruit.
  • Avoid Gala, Fuji and Red Delicious apples as these often turn a little mushy and watery when cooked.
 
Storage instructions
This apple and blueberry crumble recipe is a fantastic option if you are looking for a make-ahead dessert. Once cooked it can be cooled, covered and stored in the fridge for up to 3 days. When ready to serve it, simply reheat it in a low oven (140C/ 275F/ GM 1) for 20-25 minutes.
It can also be frozen for up to 3 months. When ready to use it, let the crumble defrost fully before reheating it in the oven as instructed above.
