Why it works: Flour and raisin match in chemistry and in kitchens. They rank in the top 1% of all ingredient pairs, and cooks put them together in 9,075 recipes. Both carry isobutyraldehyde, which smells malty, green. The science ↓

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Suet
- Adds richness and a moist, tender texture as it melts during cooking.
- Bread crumbs
- Absorb liquid and give the pudding its body and structure.
- Flour
- Helps bind the mixture and set its structure as it cooks.
- Eggs
- Bind the ingredients together and help set the pudding.
- Brown sugar
- Adds sweetness and a deeper, molasses-like flavour.
- Raisins
- Add concentrated sweetness and chewy texture throughout.
The step that matters
Boil the molds for 8 hours. The pudding must be sealed tightly in buttered molds and kept at a steady boil so it cooks through evenly. Water that boils dry or leaks in can make the pudding soggy or uneven.
Swap the currant
How well each one fits the dish's main ingredients (bread, flour, apple, raisin, sugar, orange, ginger):
- Figfits better
