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 ↓

Ingredients
Directions
Make the stock
In a pot, combine the pea shells and cold water with the bacon or mutton.
Boil until the shells are very soft.
Strain the liquid through a fine sieve, pressing the shells to extract all the flavor.
Add the spinach and peas
In a mortar, pound the spinach and mix it with a little of the strained liquid.
Strain the spinach mixture through a sieve and add it to the remaining liquid.
Boil gently for 30 minutes.
Add the shelled peas and cook until tender; the soup is ready.

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, sweet pea flavor and thickness of the soup.
- Bacon or mutton
- Adds fat and savory, meaty flavor to the liquid during the long simmer.
- Spinach
- Adds green color and a fresh, leafy flavor to the soup.
The step that matters
Boil gently for 30 minutes. Prolonged high heat dulls the bright green color of spinach and can break down the pea texture. A gentle simmer keeps the soup green and smooth while the flavors blend.
Swap the spinach
