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 body of the dish, providing the bulk and flavour base.
- Butter
- Adds fat and richness, giving the spinach a smooth, glossy texture.
The step that matters
Pass the spinach through a wire sieve. Boiled spinach holds a lot of water and fibrous texture. Draining and sieving it well removes excess liquid and breaks down the fibres, so the butter can coat it evenly instead of leaving it watery.
Swap the spinach
How well each one fits the dish's main ingredients (butter, pepper):

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