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 ↓
Salford Plum Pudding
Ingredients
Directions
Prepare the batter
Rub the butter into the flour.
Add the currants, bread crumbs, raisins, lemon rind, beaten eggs, mace or nutmeg, sugar, candied orange or lemon, and salt.
Mix in just enough milk to create a stiff batter.
Boil the pudding
Place the mixture in a floured cloth and tie it securely.
Boil for 5 hours.
Reboil in a clean cloth for 1.5 hours.

Butter and flour barely smell alike, yet cooks put them together in 124,287 recipes: they work on texture and structure more than aroma.
Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Flour
- Forms the bulk and structure that holds the pudding together as it cooks.
- Eggs
- Bind the mixture and help it set firm during boiling.
- Butter
- Adds richness and tenderness to the crumb.
- Bread crumbs
- Absorb moisture and lighten the texture of the dense batter.
- Raisins
- Add sweetness, chewy body and moisture to the pudding.
- Sugar
- Adds sweetness and helps give the pudding its dark, rich flavour.
The step that matters
Keeping the cloth tied and the water boiling. The cloth must be tied securely so water cannot soak into the pudding and make it heavy. The boil must be kept steady across the long cooking time so the pudding cooks through and sets evenly.
Swap the mace
How well each one fits the dish's main ingredients (butter, flour, currant, bread, raisin, lemon, egg):
- Nutmegfits better
- Cinnamonfits better
- Capersfits better
- Macethe original
Fit is the average pairing score against butter, flour, currant, bread, raisin, lemon, egg. Candidates are from the same food group and used in at least 100 recipes.
