Why it works: Pepper and celery match in chemistry and in kitchens. They rank in the top 5% of all ingredient pairs, and cooks put them together in 16,012 recipes. Both carry 4'-methylacetophenone, which smells bitter almond. The science ↓

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs

What each ingredient does

Split peas or lima beans
Break down during long boiling to form the body of the soup.
Flour
Thickens the strained liquid so the soup becomes creamy and substantial.
Butter
Adds richness and, with flour, helps form a smooth thickened base.
Salt pork
Adds savory fat and flavor that seasons the soup as it simmers.
Onions
Contribute savory aroma and sweetness as they cook down into the liquid.

The step that matters

Passing the mashed mixture through a sieve. Pushing the cooked peas through a sieve separates the smooth pulp from skins and fibres. Skipping or rushing this leaves a grainy texture, and the thickening that follows depends on a smooth liquid.

Swap the peas

How well each one fits the dish's main ingredients (onion, pepper, butter, flour, pork, celery, bread):

  1. Beansfits better
  2. Chestnutfits better
  3. Lentilsfits better
  4. Peasthe original

Fit is the average pairing score against onion, pepper, butter, flour, pork, celery, bread. Candidates are from the same food group and used in at least 100 recipes.
