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
Ingredients
Directions
Prepare the spinach
Wash the spinach thoroughly in several washes to remove grit.
If the spinach is young, place it in a saucepan without additional water; if it is old, add boiling water with salt.
Cook the spinach with the lid off until tender, stirring occasionally if no water is used.
Drain the spinach in a colander and wring it dry in a cloth.
Chop or rub the spinach through a wire sieve.
Sauté and serve
In a saucepan, mix the spinach with butter, pepper, and salt over heat.
Optionally, add cream but avoid making it too moist.
Press the mixture into a mound or pyramid shape in a serving dish and garnish with fried croutons or sautéed potatoes.

Pepper and cream barely smell alike, yet cooks put them together in 21,449 recipes: they work on texture and structure more than aroma.
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; cooking softens its leaves and wringing out excess water concentrates its flavour.
- Butter
- Adds fat and richness, carrying flavour and giving the spinach a glossy, smooth texture.
- Cream
- Optionally adds richness and a silkier texture, but too much adds moisture that loosens the dish.
The step that matters
Wringing the spinach dry. Spinach holds a lot of water. If excess moisture stays in, the spinach becomes soggy and diluted, so it should be drained and squeezed in a cloth before the butter is added.
Swap the spinach
How well each one fits the dish's main ingredients (butter, pepper, cream):
- Potatofits better
- Spinachthe original
- Capsicumfits about as well
- Onionfits about as well
Fit is the average pairing score against butter, pepper, cream. Candidates are from the same food group and used in at least 100 recipes.
