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 ↓
Plum Pudding
Ingredients
Directions
Prepare the mixture
In a large bowl, mix the stale bread crumbs, flour, brown sugar, chopped apples, candied peel, ground ginger, and salt.
Add the finely chopped suet, pitted raisins, cleaned currants, and chopped almonds to the mixture and combine well.
Cook and serve
Transfer the mixture into a well-greased basin and cover it with a cloth.
Boil the pudding for four hours.
Serve with brandy or sweet sauce.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Stale bread crumbs
- Absorb moisture and give the pudding its body and crumb.
- Suet
- Adds fat that keeps the pudding moist and rich as it cooks.
- Flour
- Helps bind the mixture so it holds together when cooked.
- Brown sugar
- Adds sweetness and a deeper, molasses-like flavour.
- Raisins
- Add concentrated sweetness and chewy texture throughout the pudding.
- Apples
- Add moisture and tartness that balances the sweetness.
The step that matters
Boil the pudding for four hours. The pudding must be kept at a steady simmer for the full time, because the long, gentle heat cooks the dense mixture through and sets its texture. Letting the water boil dry or drop too low can leave it heavy or undercooked in the centre.
Swap the currant
How well each one fits the dish's main ingredients (bread, flour, sugar, apple, ginger, raisin, almond):
- Figfits better
- Vanillafits better
- Apricotfits better
- Currantthe original
Fit is the average pairing score against bread, flour, sugar, apple, ginger, raisin, almond. Candidates are from the same food group and used in at least 100 recipes.
