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 dish's body; cooking softens its leaves until tender and collapsible.
- Butter
- Adds fat and richness, coating the chopped spinach for a smoother mouthfeel.
The step that matters
Pressing and draining the spinach. Spinach holds a lot of water. Pressing out the excess after boiling keeps the chopped leaves from becoming watery and diluting the butter, so the final dish stays concentrated in flavour and texture.
Swap the spinach

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