Why it works: Pepper and parsley match in chemistry and in kitchens. They rank in the top 2% of all ingredient pairs, and cooks put them together in 34,122 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
- Beef
- Provides the meat and rich savoury flavour of the soup as it simmers.
- Green peas
- Add sweetness, body and the main vegetable flavour of the soup.
- Rice flour
- Thickens the soup as it is stirred in, giving it a fuller texture.
The step that matters
Stir in the rice flour and stir frequently. Rice flour thickens as it heats and can settle and burn on the bottom of the pot. Stirring often keeps it dispersed and prevents scorching, which would give the soup a bitter, burnt taste.
Swap the peas
How well each one fits the dish's main ingredients (beef, rice, flour, pepper, parsley):
- Black-eyed peafits better
- Chickpeafits better
- Beansfits better
- Peasthe original
Fit is the average pairing score against beef, rice, flour, pepper, parsley. Candidates are from the same food group and used in at least 100 recipes.
