Apple Crumble

Bramleys tossed with a little cornflour so the juices thicken instead of flooding, under a lumpy oat topping that is never pressed down.

    • plain flour 200 g
    • unsalted butter 125 g
    • demerara sugar 75 g
    • rolled oats 50 g
    • ground almonds (optional) 50 g
    • fine salt a pinch

    Stop while pea-sized lumps remain — those are the crunchy bits.

  2. Toss the apples with the sugar, cornflour and lemon

    • bramley apples 900 g
    • caster sugar 75 g

    Rest 10 minutes before serving. Straight from the oven the fruit is molten.

Cold butter, and two teaspoons of cornflour

Rubbing cold butter into flour coats the particles in fat without melting them. In the oven those butter pockets melt and boil, steaming the crumb apart into loose, sandy clumps — the same shortening effect that makes pastry flaky, only uncontrolled, which is exactly what you want. Underneath, Bramleys are unusually acidic and high in water, and they collapse. The cornflour gelatinises in that released juice and turns it into a syrup that clings to the fruit rather than soaking the topping from below.

Notes

  • Chunks, not slices. Slices disintegrate completely in 45 minutes.
  • Eating apples hold their shape but taste flat. If you use them, halve the sugar and add extra lemon.
  • Any leftover topping freezes raw for months and goes straight from freezer to oven.

Try butter, 30 minutes, braise, or an ingredient you need to use up.
