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 ↓
Berlin Spinach
Ingredients
Directions
Prepare the spinach
Wash the spinach thoroughly to remove all sand.
Drain the spinach and place it in a large kettle without adding water.
Sprinkle with ¼ teaspoon of coarse sea salt for each 2 quarts of spinach.
Cover the kettle and toss the leaves occasionally to ensure even cooking.
When tender, drain the spinach in a colander and chop it finely.
Make the cream sauce
In a saucepan, make a cream sauce by combining 1 cup of milk with 1 heaping tablespoon of flour, seasoning with salt and pepper, and adding 1 tablespoon of butter.
Stir the chopped spinach into the cream sauce until heated through.
Serve
Serve in a vegetable dish and garnish with slices of hard boiled eggs.

Flour and butter barely smell alike, yet cooks put them together in 124,287 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
- Fresh spinach
- Cooks down in its own moisture to become tender, forming the bulk of the dish.
- Milk
- Forms the liquid base of the cream sauce, giving it a smooth, pourable body.
- All-purpose flour
- Thickens the milk into a cream sauce as its starch gelatinizes when heated.
- Butter
- Adds fat for richness and a smooth mouthfeel in the cream sauce.
The step that matters
Cooking the spinach without added water. Spinach holds enough moisture to steam in a covered kettle. Tossing it helps it cook evenly, and draining it well before chopping keeps excess water from thinning the cream sauce.

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