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 ↓
Dried Pea Soup
Ingredients

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):
- Beansfits better
- Chestnutfits better
- Lentilsfits better
- 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.
