Ingredients
Method
- Preheat oven to 190°C / 170°C fan / Gas 5. Put halved plums into ovenproof dish. Scatter brown sugar — add cinnamon stick, star anise, and water. Toss gently. Taste and adjust sugar.
- Mix flour, oats, brown sugar, cinnamon, and salt. Rub in cold butter to rough, clumpy crumbs — some larger pieces are fine.
- Scatter crumble loosely over plum filling — covering completely, right to the edges. Do not press down.
- Bake 35–40 minutes until crumble is deeply golden and filling bubbling at edges. Rest 5 minutes. Serve with warm custard.
Notes
Use Victoria plums in season — the finest plum crumble requires the finest plums.
Whole spices give gentle depth — they infuse the juices without dominating the filling.
Do not press the crumble — a loose topping bakes to a crisper, more varied golden texture.
Taste a raw plum and adjust sugar — plum tartness varies enormously.
Oats in the crumble give a nuttier, more interesting texture that suits plum specifically.
Freeze assembled before baking for up to 3 months.
