Why it works: Peas and rice match in chemistry and in kitchens. They rank in the top 4% of all ingredient pairs, and 1,405 recipes mention both. Both carry 2,4-nonadienal, which smells fatty, green. The science ↓
The recipe
Ingredients
Contains: milk (auto-detected from the ingredients and method; we can miss things, so check labels)
Directions
Prepare the peas
Melt the butter in a pan.
Fry the green peas over high heat.
Pound the peas very fine with some broth in a mortar.
Strain the peas through a fine sieve.
Make the soup
Add the strained peas to a pan with the stock and bring to a boil.
Let it boil until the fat and scum rise to the top, then skim the fat and scum off.
Add the boiled rice and sugar to the soup.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Green peas
- Form the main body and flavour of the soup once pounded and strained.
- Butter
- Adds fat and richness, carrying flavour as the peas are fried.
- Rice
- Adds body and thickness to the finished soup.
- Sugar
- Adds sweetness that balances the savoury peas and stock.
The step that matters
Straining the pounded peas. Pressing the pounded peas through a fine sieve removes fibrous skins and lumps, giving a smooth texture. Skipping or rushing this leaves the soup grainy.
Flavor stand-ins for the peas
How well each one fits the dish's main ingredients (butter, rice, sugar):

- Beansbetter flavor fit
- Peasthe original
Fit is the average pairing score against butter, rice, sugar. Candidates are from the same food group and used in at least 100 recipes. This compares flavor only: it does not check the job the ingredient does in the dish (bulk, moisture, acidity, structure).
