Why it works: Beans and mustard match in chemistry and in kitchens. They rank in the top 4% of all ingredient pairs, and cooks put them together in 852 recipes. Both carry 2-isopropyl-3-methoxypyrazine, which smells earthy, pea. The science ↓
Puree of Beans
Ingredients
Directions
Prepare
Soak the beans in cold water overnight.
Make the puree

Finish and serve
Just before serving, stir in the prepared mustard and season with salt and cayenne.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Pea beans
- Break down into a thick, smooth body when cooked and pureed, giving the puree its texture.
- Stock
- Cooks the beans and supplies the savory liquid base of the puree.
- Onion
- Softens during boiling and adds a mild, aromatic sweetness to the stock.
- Prepared mustard
- Adds sharp, pungent flavor that brightens the rich, starchy puree.
The step that matters
Cook the beans until thoroughly tender. Beans must be fully softened so their starch and cell walls break down completely. Undercooked beans stay grainy and will not rub through the sieve into a smooth puree.
Swap the onion
How well each one fits the dish's main ingredients (beans, mustard):
- Lettucefits better
- Horseradishfits better
- Welsh onionfits better
- Onionthe original
Fit is the average pairing score against beans, mustard. Candidates are from the same food group and used in at least 100 recipes.
