Plum Crumble

Instructions

1. Heat the oven to 375°F (190°C) and place a 2-quart baking dish on a rimmed baking sheet.

2. In a large bowl, combine the plums, granulated sugar, lemon juice, and cornstarch; toss until the fruit is evenly coated, then scrape into the baking dish and spread in an even layer.

3. In another bowl, whisk together the all-purpose flour, light brown sugar, and fine sea salt. Add the unsalted butter and rub it into the dry ingredients with your fingertips until you have coarse crumbs with some larger clumps.

4. Scatter the crumble evenly over the fruit, leaving a few small gaps for steam to escape.

5. Bake until the topping is deep golden and the juices are bubbling thick around the edges, 40–50 minutes; tent loosely with foil if the topping browns too quickly.

6. Let cool for 15 minutes so the juices set. Serve warm with vanilla ice cream (for serving).

Plum Crumble is a warmly scented baked dessert that pairs tender, tangy-sweet plums with a sandy, buttery topping. The fruit cooks down into a jammy layer, while the crumble bakes to a crisp, golden finish with pleasing contrast in every bite. It’s straightforward to assemble, deeply comforting, and showcases late-summer stone fruit at peak ripeness.

Historically, crumble is a British creation that rose to prominence in the mid-20th century, when rationing made elaborate pastry less practical. Simple pantry staples—flour, sugar, and fat—were rubbed together to top seasonal fruit, offering a thrifty alternative to pies. Plums have long been a favored filling across the UK, making plum crumble a perennial classic in home kitchens and pubs alike.
