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

Prepare the spinach
Cook the spinach in salted boiling water until tender.
Drain the spinach in a colander and chop it finely.
In a pan, fry the chopped spinach with butter, pepper, and salt for a few minutes.

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 earthy flavour of the dish, softened by cooking and then chopped fine.
- Butter
- Adds fat and richness, carrying flavour as the spinach fries.
- Hard boiled eggs
- Add protein and a creamy, mild richness that balances the spinach.
- Bread
- Forms the crisp toasted base that holds the spinach and eggs.
The step that matters
Drain the spinach thoroughly after cooking. Spinach holds a lot of water. Excess moisture left in it dilutes the flavour and makes the toast soggy, so squeezing or draining well before frying keeps the filling thick and the bread crisp.
Swap the spinach
How well each one fits the dish's main ingredients (butter, pepper, egg, bread):
- Capsicumfits better
- Asparagusfits better
- Chivefits about as well
- Spinachthe original
Fit is the average pairing score against butter, pepper, egg, bread. Candidates are from the same food group and used in at least 100 recipes.
