Why it works: Spinach and pepper are a kitchen classic. They rank in the top 6% of all ingredient pairs, and cooks put them together in 3,400 recipes. Both carry nonanal, which smells fat, citrus. The science ↓
Spinach Balls
Ingredients
Directions
Prepare
Combine finely chopped spinach and dry bread crumbs in a bowl.
Season with pepper, coarse sea salt, and cayenne to taste.
Add enough egg white to moisten the mixture and let it sit to stiffen.
Shape and poach

Poach the balls in hot soup for five minutes.
Serve
Serve three or four balls in each plate of clear soup.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Spinach
- Provides the bulk and green flavour of the balls and keeps them moist.
- Dry bread crumbs
- Absorb moisture and bind the spinach so the balls hold their shape.
- Egg white
- Sets when heated and binds the mixture together.
The step that matters
Adding the egg white. Too little egg white leaves the balls crumbly and they fall apart in the soup, while too much makes them wet and dense. Letting the mixture rest lets the crumbs absorb the moisture so it stiffens enough to shape.
Swap the spinach
How well each one fits the dish's main ingredients (bread, pepper, egg):
- Capsicumfits better
- Asparagusfits about as well
- Spinachthe original
- Tomatofits about as well
Fit is the average pairing score against bread, pepper, egg. Candidates are from the same food group and used in at least 100 recipes.
