Why Bramleys Beat Every Other Apple in a Crumble

Eat a Bramley raw and you will pull a face. That is precisely the point. Its fierce acidity and high pectin content mean it collapses on cooking into a soft, fluffy, faintly tart purée rather than holding its shape like a Cox or a Gala. That collapse is exactly what a crumble needs: a filling with body and bite, sharp enough to cut through a sweet, buttery topping.

Autumn is when Bramleys are at their best, harvested from late August through October and happy in a cool, dark place for weeks afterwards. Buy them firm, heavy and green-flushed, with no soft brown patches. A crumble made with Bramleys tastes of the season; one made with dessert apples tastes of sugar.

Preparing the Fruit Properly

For a dish serving six, you want about 900g of peeled, cored Bramley apples — roughly 1.2kg whole. Peel them thickly, quarter, cut out the core, then slice each quarter into three or four chunky pieces. Resist the urge to dice them small; larger slices give you pockets of soft fruit rather than a uniform mush.

Tumble the slices into a bowl with:

• 60g caster sugar — more if your apples are particularly sharp, less if you like a bracing pudding
• 1 teaspoon ground cinnamon and a small pinch of ground cloves
• 1 tablespoon lemon juice, which sharpens the flavour rather than souring it
• 1 heaped teaspoon cornflour if your apples are very juicy, to stop the base turning to soup

Stir well and leave the fruit to sit while you make the topping. That ten minutes draws out some juice and lets the spices bloom.

The Topping: Oats, Demerara and Cold Butter

A proper crumble topping is rubbly and uneven, never a smooth pastry lid. Work quickly and keep everything cold. In a large bowl, combine 175g plain flour with 100g cold unsalted butter cut into cubes. Rub the butter in with your fingertips, lifting the mixture high as you go to keep it airy, until you have coarse breadcrumbs with a few pea-sized lumps left in.

Now stir through 75g demerara sugar, 60g porridge oats, a good pinch of fine salt and, if you like, 30g flaked almonds or chopped hazelnuts. The demerara gives a toffee crunch as it melts; the oats keep the topping from turning into a solid biscuit. Don't squeeze it together — clumps are welcome, but a compressed layer will bake hard.

Layering and Baking

Heat the oven to 200°C (180°C fan, gas mark 6). Tip the apples and their juices into a roughly 1.5-litre ovenproof dish — something about 23cm by 20cm and at least 6cm deep, so the fruit bubbles up rather than over. Level the surface, then scatter the topping over in an even layer. Don't press it down.

Bake on the middle shelf for 40 to 45 minutes, until the topping is deep golden and you can see thick juices bubbling at the edges of the dish. If the top is colouring faster than the fruit is cooking, lay a sheet of foil loosely over it after half an hour. If you want extra crunch, scatter a final tablespoon of demerara over the top ten minutes before the end.

Then do the hard part: rest it for ten minutes before serving. The filling settles, the juices thicken and you avoid scalding the roof of your mouth on molten apple.

Seasonal Twists Worth Trying

The basic recipe is a template, and autumn gives you plenty to work with.

• Blackberry and apple: fold 200g of hedgerow blackberries through the apples in September — no extra sugar needed.
• Pear and ginger: swap a third of the Bramleys for firm pears and add a tablespoon of chopped stem ginger plus a spoonful of its syrup.
• Dried fruit: a handful of sultanas or chopped dates soaked in orange juice adds a deep, wintry note from November onwards.
• Nutty topping: replace 40g of the flour with ground almonds for a softer, frangipane-like crumb.

Rhubarb works on the same principle in spring, but that is another article entirely.

Serving, Storing and Reheating

Custard is the classic, and homemade is worth the ten minutes: warm 500ml of whole milk with a split vanilla pod, whisk into four egg yolks and 50g caster sugar, then stir over a low heat until it coats the back of a spoon. Failing that, a good tin of custard, gently warmed, is nobody's hardship. Cold double cream, clotted cream or a scoop of vanilla ice cream all have their advocates, and all are correct.

Leftovers keep covered in the fridge for three days. Reheat in a moderate oven, uncovered, for 15 minutes — the microwave will soften the topping and undo your good work. Cold crumble for breakfast, incidentally, is one of the great quiet pleasures of a British autumn, and I will not be arguing about it.
