Why it works: Carrot and potato match in chemistry and in kitchens. They rank in the top 4% of all ingredient pairs, and cooks put them together in 3,107 recipes. Both carry 2-isobutyl-3-methoxypyrazine, which smells green bell pepper, earthy. The science ↓

Flour and butter 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
- Provides the main structure and body that holds the pudding together.
- Currants
- Add sweetness and a chewy texture as dried fruit.
- Grated carrots
- Add moisture and gentle sweetness to the mixture.
- Grated potatoes
- Their starch helps bind the mixture and adds moisture.
- Butter
- Adds fat for richness and a tender, moist crumb.
- Sugar
- Adds sweetness and balances the savoury notes of the vegetables.
The step that matters
Boiling the mixture for 1.5 hours. A steady, sustained boil cooks the flour and potato starches through, so the pudding sets and holds together. Stopping early leaves it raw in the centre and loose in texture.

Fit is the average pairing score against flour, carrot, potato, butter, sugar. Candidates are from the same food group and used in at least 100 recipes.
