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 ↓

Prepare the spinach
Clean the spinach, then cut it into pieces and wash it well.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Spinach
- Forms the bulk of the dish and gives it its body and green flavour.
- Flour
- Fried in butter, it thickens the broth into a smooth sauce.
- Butter
- Carries the flour for frying and adds richness to the sauce and bread.
- Broth
- Liquid that loosens the spinach and flour into a sauce with savoury flavour.
- Stale bread
- Fried in butter, it adds crisp texture and contrast to the soft spinach.
The step that matters
Frying the flour in the butter. Flour must be cooked in fat long enough to lose its raw taste and to thicken evenly. If it is added to liquid unevenly or stays raw, the sauce will be lumpy or taste floury.
Swap the spinach
How well each one fits the dish's main ingredients (flour, butter, milk, bread, pepper):
- Capsicumfits better
- Potatofits better
- Shallotfits about as well
- Spinachthe original
Fit is the average pairing score against flour, butter, milk, bread, pepper. Candidates are from the same food group and used in at least 100 recipes.
