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 ↓
Boiled Spinach
Ingredients
Directions
Prepare
Carefully pick over and wash the spinach in several waters, letting it soak in the last wash for 30 minutes.
Shake each bunch well and place it in boiling water with a little salt.
Cook and serve
Boil for about 20 minutes or until tender, then drain and chop finely.
In a saucepan, combine the chopped spinach with butter, salt, and pepper, and stir until very hot.
Transfer to a dish and slice hard boiled eggs over the top.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Spinach
- Forms the main body of the dish, softening as it boils and wilts into a tender mass.
- Butter
- Adds fat and richness, coating the chopped spinach and giving it a smooth mouthfeel.
- Hard boiled eggs
- Add protein and a mild, creamy contrast to the soft, earthy spinach.
The step that matters
Washing the spinach thoroughly. Spinach leaves trap sand and grit in their folds, so soaking and rinsing in several changes of water removes it. Grit left behind is unpleasant and hard to notice until eaten.
