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 ↓

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; blanching softens it and chopping gives it a finely textured base.
- Butter
- Adds fat and richness, coating the spinach and carrying its flavor.
- Eggs
- Add protein and a firm, mild contrast to the soft spinach as a garnish.
The step that matters
Drain the blanched spinach well before chopping. Spinach holds a lot of water. Any left over dilutes the butter and seasoning and leaves the dish watery.
Swap the spinach
How well each one fits the dish's main ingredients (egg, butter, pepper):

Fit is the average pairing score against egg, butter, pepper. Candidates are from the same food group and used in at least 100 recipes.
