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
Remove the stalks from the spinach leaves.
Wash the leaves in cold water two or three times.
Drain the spinach in a colander.
Place the spinach in a large saucepan, sprinkle with salt, and boil without adding water for 10 minutes with the cover off.
Drain the spinach again and press out all the water until dry.
Chop the spinach finely or rub it through a wire sieve if preferred.
Make the creamed spinach
In a stewpan, melt 1 ounce of butter, then add the spinach, pepper, salt, and cream, mixing well.
Heat the mixture on the stove, stirring until hot.
Make the toasted bread
Cut a slice of bread into triangular pieces.
In a frying pan, heat 2 ounces of butter or clarified dripping.
Fry the bread pieces in the hot fat until pale brown.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Spinach
- Forms the bulk of the dish and, once pressed dry, gives a concentrated green flavour.
- Butter
- Adds richness and fat, carrying flavour and helping the spinach feel smooth.
- Cream
- Adds moisture and richness, helping the chopped spinach become a smooth, spoonable mixture.
- Bread
- Toasted in hot fat, it browns and crisps, adding contrast to the soft spinach.
The step that matters
Press the spinach dry. Spinach holds a lot of water. Any left behind dilutes the cream and makes the mixture watery, so pressing it fully dry keeps the final texture thick and creamy.
Swap the spinach
How well each one fits the dish's main ingredients (butter, cream, pepper, bread):

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