Why it works: Peas and lettuce match in chemistry and in kitchens. They rank in the top 5% of all ingredient pairs, and cooks put them together in 1,293 recipes. Both carry 2-isobutyl-3-methoxypyrazine, which smells green bell pepper, earthy. The science ↓
Green Pea Puree
Ingredients

Cook for a few minutes.
Serve

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Green peas
- Provide the main body and flavour of the puree once cooked and sieved.
- Rice flour
- Thickens the soup as it heats, giving it a smooth, body-rich texture.
- Cream
- Adds richness and fat, softening the flavour and smoothing the finished soup.
- White stock
- Forms the cooking liquid that carries flavour and makes the puree pourable.
The step that matters
Add the blended rice flour and bring to a boil. Rice flour must be fully blended into liquid before it goes in, and the soup must reach a boil so the starch thickens and cooks out any raw floury taste. Adding it lumpy or undercooking it leaves a grainy or pasty texture.
Swap the peas
How well each one fits the dish's main ingredients (cream, rice, flour, lettuce):
- Cashew nutfits better
- Almondfits better
- Chestnutfits better
- Peasthe original
Fit is the average pairing score against cream, rice, flour, lettuce. Candidates are from the same food group and used in at least 100 recipes.
