A Pudding Worth Keeping in Your Repertoire

There are few things more reassuring than an apple crumble coming out of the oven on a grey afternoon. The smell alone — tart fruit, warm cinnamon, hot butter — is enough to draw everyone into the kitchen. It is a genuinely British institution, born of wartime thrift and never bettered: soft, slightly sharp apples underneath, a crisp, buttery rubble of a topping above, and a jug of custard waiting nearby.

Better still, it is one of the most forgiving puddings you can make. It costs very little, uses up apples that have gone a bit soft in the bowl, and can be assembled in the time it takes the oven to heat. Get the basics right and you will make it for years.

Choose Your Apples — and Balance the Sweetness

You want apples that collapse rather than hold their shape. Bramleys are the classic choice, and about 1kg — roughly four or five large ones — is the right amount for a family-sized dish. If you only have eating apples in the fruit bowl, use them, but mix in a Bramley if you can: cookers give that lovely fluffy texture and a proper tang, while eaters bring flavour and a little structure.

For the filling you will need:

• 1kg cooking apples, peeled, cored and cut into 2cm chunks
• 50–100g caster sugar, depending on how sharp your apples are
• 1 tsp ground cinnamon and a ¼ tsp mixed spice
• 1 tbsp plain flour or cornflour to thicken the juices
• A squeeze of lemon juice or the zest of half a lemon
• A knob of butter for greasing the dish

Taste a raw slice of apple before you commit. If it makes you wince, go closer to 100g of sugar; if it is mild, 50g will do. Toss everything together in a bowl and leave it to sit while you make the topping — the sugar will start drawing out the juices.

The Topping: Rub, Don't Overwork

A good crumble topping should be rubbly and uneven, never a smooth dough. You need:

• 175g plain flour
• 100g cold butter, cut into cubes
• 75g demerara sugar for crunch
• 75g porridge oats (jumbo oats give the best texture)
• A good pinch of fine salt

Tip the flour into a large bowl, add the butter and rub it in with your fingertips, lifting and crumbling as you go. Stop when it looks like coarse breadcrumbs with a few pea-sized lumps left in — those lumps are what make the topping crisp and short. Stir through the sugar, oats and salt. If you want extra crunch, add a handful of flaked almonds or chopped hazelnuts. Never add water, and don't be tempted to squeeze it together.

Assembling and Baking

Butter a shallow ovenproof dish of about 1.5–2 litres. Tip in the apples and level them gently — don't press them down hard, or you will lose the juices. Scatter the topping over the fruit in an even layer, again without compacting it. A loose, airy topping browns far better than a pressed one.

Bake at 180°C fan / 200°C / gas mark 6 for 35–45 minutes. You are looking for a deep golden top and juices bubbling up around the edges. If the crumble is colouring too quickly, lay a sheet of foil loosely over the top. When it comes out, leave it to settle for ten minutes before serving — the filling is molten straight from the oven and will firm up beautifully as it rests.

Serve It Properly

Custard is the traditional partner, and proper homemade custard is worth the effort: thick enough to coat the back of a spoon, heavy with vanilla. Failing that, a really good shop-bought chilled custard beats a powdered one every time. Double cream, clotted cream or a scoop of vanilla ice cream all have their advocates, and there is no wrong answer. A little pouring cream alongside custard is not excessive; it is considerate.

Cold crumble for breakfast, incidentally, is one of the great unsung pleasures of a British kitchen. A spoonful with thick yoghurt and a few berries makes an excellent start to the day.

Riffs, Leftovers and Small Mercies

Once you are confident with the method, the variations write themselves:

• Swap the fruit — pears, plums, rhubarb, damsons and blackberries all work, though rhubarb needs more sugar
• Add depth — a spoonful of mincemeat, a splash of ginger wine, or a little chopped stem ginger in the fruit
• Change the spice — ground ginger, nutmeg or a pinch of cardamom in place of cinnamon
• Make it ahead — assemble completely, cover and chill for up to 24 hours, then bake from cold, adding 10 minutes
• Freeze it — unbaked crumble freezes well for up to three months; bake from frozen at the same temperature, allowing an extra 20 minutes

Leftovers keep in the fridge for up to three days. Reheat, covered, at 180°C for 15 minutes, or give a portion a quiet minute in the microwave — no one is watching.
