Why it works: Parsley and pepper 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
- Peas
- Form the main body and sweet, vegetal flavour of the soup.
- Second stock
- Provides the liquid base that carries the flavour of the soup.
- Spinach
- Adds leafy flavour and a deeper green colour to the soup.
- Sugar
- Rounds out the flavour and balances the vegetal bitterness of the peas.
The step that matters
Boil for 1 hour. Boiling the peas long enough softens them fully so they can be pushed through a sieve smoothly. Under-cooked peas leave a grainy, starchy texture.
Swap the peas
How well each one fits the dish's main ingredients (parsley, mint, sugar, spinach, pepper):
- Chickpeafits better
- Lentilsfits better
- Cashew nutfits better
- Peasthe original
Fit is the average pairing score against parsley, mint, sugar, spinach, pepper. Candidates are from the same food group and used in at least 100 recipes.
