The Sunday Pudding Ledger: 14 Supermarket Apple Crumbles, Ranked by Crunch and Custard Greed
A good apple crumble is not a dessert. It is a negotiation between crunch, fruit and custard. Get it right and Sunday feels sorted. Get it wrong and you are eating sweetened sawdust with a side of sadness.
That is why, on a grey November weekend in 2026, we bought 14 supermarket apple crumbles — five chilled, five frozen, four ready-to-bake — covered the packaging, and blind-tasted them in the BiteIt kitchen. We scored topping crispness out of 40, fruit-to-topping ratio out of 30, sweetness out of 15 and reheating performance out of 15. Then we did the custard maths.
This is not a beauty parade. It is a ledger.
How we tested, and why the custard mattered
Chilled and ready-to-bake crumbles went into a 180C fan oven for the pack time plus five minutes. Frozen ones went in from frozen at 190C fan. We let everything stand for ten minutes, then tasted blind. Leftovers were reheated the next day at 160C fan for 12 minutes, because a crumble that only works on day one is not a proper Sunday pudding.
The custard test was simple: one tablespoon of hot custard per 100g of crumble, poured at the table. If a portion needed three or more tablespoons just to become edible, it lost points. Custard should finish a crumble, not rescue it.
The topping test: crunch, clag and the soggy middle
The best toppings had visible oat clusters, a proper butter rub and a mix of big and small crumbs. They stayed crisp on top and slightly chewy underneath. The worst were fine breadcrumb dust that turned to paste before the custard hit the bowl. A few looked promising raw and then collapsed into a single pale blanket.
Our rule: if the topping looks like sand before baking, it will taste like wet sand after. You want rubble, not powder.
Fruit maths: where the apple actually went
We aimed for a fruit-to-topping ratio of roughly 45:55 by weight. Several crumbles were closer to 30:70. That is not a crumble; that is a biscuit with apple garnish. The best had soft but distinct apple pieces, a bit of Bramley tang and enough syrup to coat the fruit without flooding the base.
Sweetness was the quiet killer. A crumble can be sweet, but it needs lemon, cinnamon or sharp apple to stop it tasting like pudding syrup. The ones that got this right were the ones we went back to for a second spoon.
The custard index
Custard is not a sauce. It is a stress test. A good crumble holds a glossy pool on top without instantly turning to mush. It also does not demand a second jug. Our top scorers needed about one and a half tablespoons per portion. The bottom scorers drank custard like a sponge and still tasted dry.
Reheatability: the Wednesday test
Leftovers separate the real crumbles from the show-offs. The best re-crisped in the oven and kept their fruit juicy. The worst went dense and gloomy, with a topping that tasted like damp flapjack. Microwave only as an emergency. An air fryer at 160C for five to six minutes is the best shortcut for a single portion.

The winners, and the rescue jobs
Best overall was C7, a frozen standard family crumble. It had the crunchiest topping, a generous apple layer and the best reheat. It is the one to keep in the freezer for a Sunday when you cannot be bothered.
Best chilled was C2. It tasted fresher than most, with a good sharp apple edge and a topping that stayed crisp. Best ready-to-bake was C12: not fancy, but reliable, and it improved with an extra chopped Bramley and a pinch of demerara on top.
C3, C13 and C14 need help. If your crumble is pale and claggy, spread it into a shallower dish, scatter with demerara and a few knobs of butter, then blast at 200C for five minutes. If the fruit is sharp, add a teaspoon of sugar. If the topping is already dark, cover it with foil first.
The Sunday verdict
For low-effort pudding, buy a frozen standard crumble and a tub of proper custard. For something that tastes closer to homemade, buy ready-to-bake and add fresh apple. Skip the value chilled crumbles unless you enjoy kitchen DIY.
Crumble is forgiving. But not that forgiving. The best ones earn their custard; the worst ones need a rescue mission and a stern word.
