Why it works: Peas and spinach work together. They rank in the top 8% of all ingredient pairs, and cooks put them together in 550 recipes. Both carry 2-isobutyl-3-methoxypyrazine, which smells green bell pepper, earthy. The science ↓

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Green peas
- Provide the body and the sweet, vegetal base flavor of the soup.
- Spinach
- Adds earthy flavor and the soup's green color.
- Bacon or mutton
- Adds fat and savory, meaty depth to the cooking liquid.
The step that matters
Boil the spinach mixture gently. Green color comes from chlorophyll, which breaks down and turns dull olive when spinach is boiled hard or for too long. A gentle simmer keeps the soup bright green.
Swap the spinach
How well each one fits the dish's main ingredients (peas, mutton):
- Asparagusfits better
