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
- Ox cheek
- Long, gentle simmering breaks down its connective tissue, giving tender meat and a rich body to the broth.
- Split peas, barley, or white haricot beans
- Starchy grains and legumes thicken the soup and add body as they cook.
- Flour
- Starch that thickens the liquid when used for thickening.
The step that matters
Skimming the fat. Fat that rises during simmering can make the soup greasy and cloudy. Removing it as it forms keeps the broth clean and lighter in texture.
Swap the peas
The recipe marks peas as optional. How well each one fits the dish's main ingredients (pepper, celery, rice, flour):
- Black-eyed peafits better
- Beansfits better
- Lentilsfits better
- Peasthe original
Fit is the average pairing score against pepper, celery, rice, flour. Candidates are from the same food group and used in at least 100 recipes.
