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 structure that holds the pudding together as it cooks.
- Suet
- Adds richness and moisture, giving the pudding a tender, crumbly texture.
- Mashed potatoes
- Adds body and moisture, helping the pudding stay soft without eggs.
- Mashed carrot
- Adds moisture and body, helping bind the mixture without eggs.
- Brown sugar
- Adds sweetness and a deeper, molasses-like flavour.
The step that matters
Leave room for swelling. The mixture expands as it cooks and gains moisture from steaming. Packing it tightly in the cloth or basin can cause it to burst or cook unevenly, so it should be filled loosely.
Swap the currant
How well each one fits the dish's main ingredients (flour, raisin, sugar, carrot, potato, lemon):
- Orangefits better
- Limefits better
- Figfits better
- Currantthe original
Fit is the average pairing score against flour, raisin, sugar, carrot, potato, lemon. Candidates are from the same food group and used in at least 100 recipes.
