An Autumn Pie Worth the Walk

There is a moment in early September, usually on a blustery coastal path somewhere in Pembrokeshire or Northumberland, when the scent of brambles mixes with salt air and you realise the season has turned. The blackberries are fat and dark, the apples are dropping in the orchard, and the evenings have that first proper chill that demands something warm from the oven.

This crumble pie sits happily between two British classics. You get the buttery, oaty rubble of a crumble and the deep, jammy fruit of a proper apple pie. It is forgiving enough for a Tuesday night and handsome enough for Sunday lunch with the family. Best of all, it uses whatever the hedgerows and the garden give you.

Choosing Your Apples and Blackberries

For the apples, you want a mix. Bramleys give you the sharpness and the collapse-into-softness that makes the fruit filling sing, but if you use them alone the pie can turn to mush. Pair roughly two parts Bramley with one part something firmer — a Cox, a Russet, or a Discovery if you can still find them. Peel, core and slice them about a centimetre thick.

Blackberries are the wildcard. Foraged ones are often smaller and tarter than the supermarket punnets, which is no bad thing, but they vary wildly in sweetness. Taste as you go. If your berries are sharp, add an extra tablespoon of sugar; if they are plump and sweet, hold back.

• 900g prepared apples (peeled, cored, sliced)
• 250g blackberries, fresh or frozen
• 100g caster sugar, plus extra for the topping
• 2 tbsp cornflour
• 1 tsp ground cinnamon
• A good grating of lemon zest
• A pinch of fine sea salt

Toss the fruit with the sugar, cornflour, cinnamon, zest and salt in a large bowl and let it sit for twenty minutes. The cornflour is not optional — blackberries release a great deal of juice, and without it you will have a soggy base and a puddle on the plate.

The Pastry Base Question

Purists will tell you a crumble belongs in a dish with no pastry at all. I would gently disagree. A thin, crisp shortcrust base turns this from a pudding into a pie, catches all that bubbling fruit, and gives you something to cut through with a spoon.

Use 200g of plain flour, 100g of cold unsalted butter cut into cubes, a tablespoon of icing sugar and a beaten egg to bind. Rub the butter into the flour until it looks like coarse breadcrumbs, stir in the sugar, then bring it together with the egg. Press it into a 23cm pie dish or shallow tin, going slightly up the sides, and chill it for half an hour. Blind bake it at 190°C (170°C fan, gas mark 5) for fifteen minutes with baking parchment and rice, then five minutes without. This step is what keeps the base crisp.

The Crumble Topping

Now the part everyone fights over. The trick is texture — you want clumps, not sand. Rub 150g of plain flour with 100g of cold butter until you have a rough, pebbly mixture, then stir through 75g of demerara sugar, 50g of porridge oats and a handful of flaked almonds if you like. Demerara matters here: its molasses flavour caramelises in the oven and gives you those dark, crunchy edges.

Squeeze a few handfuls together in your fist as you scatter it over the fruit. Those pressed clumps are the bits people pick off the top before it reaches the table.

Assembling and Baking

Spoon the macerated fruit into the blind-baked base, along with any juices in the bowl — that is flavour, not waste. Pile the crumble over the top, leaving a few gaps around the edge so steam can escape, and scatter a final tablespoon of demerara over the surface.

• Bake at 190°C (170°C fan, gas mark 5) for 35–40 minutes
• Look for deep golden clumps and dark purple juice bubbling at the edges
• If the top browns too fast, tent it loosely with foil after 25 minutes
• Rest for at least 20 minutes before serving — the filling thickens as it cools

That resting time is the hardest part of the whole recipe, but cutting straight from the oven gives you fruit soup.

Serving, Storing and Seasonal Swaps

Custard is the traditional partner, and a proper homemade one made with vanilla and double cream is worth the effort. Failing that, clotted cream, or a scoop of vanilla ice cream that melts into the hot fruit. On a cold October evening, all three have their merits.

Leftovers keep covered in the fridge for three days and reheat beautifully in a low oven for ten minutes — never in the microwave, which turns the crumble to paste. Come November, swap the blackberries for sliced pears and a handful of chopped hazelnuts; in December, cranberries and a pinch of mixed spice work just as well. The structure stays the same, only the hedgerow changes.
