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 ↓
Plain Spinach
Ingredients
Directions
Boil the spinach in just enough water to prevent burning for 10 to 15 minutes with salt.
Drain the spinach, squeeze it dry, and chop it finely.
In a clean saucepan, combine the chopped spinach with butter and pepper. Stir over heat until hot, then serve on a warm dish garnished with toast.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Fresh spinach
- Forms the main body of the dish, and cooking it down concentrates its flavor.
- Butter
- Adds fat and richness, coating the spinach and giving it a smooth mouthfeel.
The step that matters
Squeezing the spinach dry. Spinach holds a lot of water after boiling. Excess liquid dilutes the butter and makes the dish soggy, so squeezing it thoroughly before chopping keeps the texture firm and the flavor concentrated.
