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
- Flour
- Provides the starch structure that holds the pudding together as it cooks.
- Suet
- Adds fat that keeps the pudding rich, tender and moist.
- Sugar
- Adds sweetness and helps balance the savoury vegetables and spices.
- Grated potatoes
- Add moisture and starch that help bind the pudding and keep it moist.
- Grated carrots
- Add moisture and natural sweetness, helping keep the pudding soft.
- Raisins
- Add concentrated sweetness and chewy texture throughout the pudding.
The step that matters
Boil the pudding for several hours. Long, gentle boiling cooks the flour and grated vegetables through and softens the suet. Too short a boil leaves the centre dense and doughy, so the pudding needs a steady, sustained simmer.
Swap the currant
How well each one fits the dish's main ingredients (flour, sugar, raisin, potato, carrot, nutmeg, orange):
- Lemonfits better
- Figfits better
- Limefits better
- Currantthe original
Fit is the average pairing score against flour, sugar, raisin, potato, carrot, nutmeg, orange. Candidates are from the same food group and used in at least 100 recipes.
