+-------------------------------------------------------------------+

Step 1: Prep Oven and Fruit Base 🍇

Preheat your oven to 190°C (170°C Fan / Gas Mark 5). Wash, halve, and pit the 750g fresh plums, then cut them into quarters. Toss the plum quarters directly into your ceramic pie dish with 50g dark brown sugar, orange zest, orange juice, ground cinnamon, and 1 tablespoon of flour until coated. Spread in an even layer.

Step 2: Rub Butter into Flour 🥣

Sift the 175g plain flour into a mixing bowl. Add the 100g cold cubed butter. Using your fingertips, rub the butter gently into the flour until the mixture resembles coarse breadcrumbs (do not over-rub into a smooth paste!).

Step 3: Stir in Sugar and Rolled Oats 🌾

Stir the 75g Demerara sugar and 50g rolled oats into the crumble mixture until evenly combined.

Step 4: Top Fruit and Add Crunch 🥧

Spoon the oat crumble topping loosely over the spiced plum filling, taking care not to pack or press the crumble down (packing makes it heavy and dense!). Scatter optional flaked almonds across the top.

Step 5: Bake to Golden Perfection 🍰

Bake on the middle shelf of your preheated oven for 35 to 40 minutes until the crumble topping is deep golden-brown, crisp, and the ruby-red plum juices are bubbling vibrantly up around the edges.

Step 6: Cool Slightly and Serve 🎨

Remove from the oven and let rest for 5 to 10 minutes to allow the bubbling fruit juices to settle. Serve hot in shallow bowls with warm vanilla custard, double cream, or vanilla ice cream!

🤫 Cook’s Secrets for Flawless Plum Crumble

Even with a simple recipe, a few professional tricks can elevate your crumble to bakery-quality standard:

1. 🧈 Keep Butter Cold: Always use cold butter when rubbing into flour. Warm butter melts into the flour, resulting in a greasy dough rather than light, crisp crumble breadcrumbs.
2. 🌾 Use Demerara Sugar in Topping: Demerara sugar has large, golden crystals that do not melt completely, providing Mary Berry’s signature crunch.
3. 🚫 Don’t Pack the Crumble Down: Sprinkle crumble loosely over the fruit. Pressing it down seals out air, preventing the topping from baking light and crisp.
4. 🌾 Add Flour to Fruit: Tossing a tablespoon of flour or cornflour with the raw plums thickens the sweet fruit juices as they bake, preventing a watery base.

❓ Frequently Asked Questions

Can I make Mary Berry plum crumble in advance?

Yes! You can assemble the unbaked crumble up to 24 hours in advance and keep it covered in the fridge. Bake straight from the fridge, adding 5 extra minutes to the baking time.

Can I freeze plum crumble?

Yes! You can freeze the assembled crumble (baked or unbaked) for up to 3 months. Thaw overnight in the fridge and bake or reheat at 180°C until piping hot.

What can I use if plums are out of season?

You can use frozen plums (thawed and drained), or swap half the plums for Bramley cooking apples or blackberries for a classic autumn fruit mix!

Why did my crumble topping turn soggy?

Crumble turns soggy if it was pressed down tightly onto the fruit, if too much fruit liquid boiled into it, or if the oven temperature was too low to crisp the butter.
