Why it works: Beans and carrot match in chemistry and in kitchens. They rank in the top 4% of all ingredient pairs, and cooks put them together in 1,443 recipes. Both carry 2-isobutyl-3-methoxypyrazine, which smells green bell pepper, earthy. The science ↓

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Dried red beans
- Form the bulk of the puree once softened and pressed smooth.
- Baking soda
- Raises the pot's pH, helping the beans soften so they can be mashed.
- Ham
- Flavours the beans as they simmer, then is removed before pureeing.
- Butter
- Adds fat for richness and a smoother, silkier mouthfeel.
- Cream (in the method)
- Loosens the mash to a soft, spoonable consistency and adds richness.
The step that matters
Boil until the beans can be easily mashed. Dried beans must cook long enough for their starch to fully gelatinise and the skins to soften; undercooked beans stay grainy and will not press smoothly through a colander.
Swap the beans
How well each one fits the dish's main ingredients (carrot, onion, ham, butter, pepper):
- Beansthe original
- Black-eyed peafits about as well
- Lentilsfits less well
- Peasfits less well
Fit is the average pairing score against carrot, onion, ham, butter, pepper. Candidates are from the same food group and used in at least 100 recipes.
