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 ↓
Modern Cookery
Ingredients
Directions
Prepare the greens
Cook the greens in boiling water for 20 to 30 minutes, depending on their age.
Drain and press out the water, then chop the greens slightly.
Make the sauce
In a clean saucepan, heat the greens with pepper, salt, and butter.
Sprinkle in the flour and stir well.
Add the broth or gravy and boil quickly until the mixture is fairly dry.
Finish and serve
Stir in the vinegar or lemon juice and serve hot with fried bread snippets.

The pairs that carry this dish. Each one is judged two ways: how much their aromas overlap, and how often cooks already put them together.

Butter and flour 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
- Greens
- Provide the main body and flavor of the dish, and their moisture is reduced by pressing and boiling.
- Flour
- Thickens the butter and broth mixture into a sauce that clings to the greens.
- Butter
- Adds richness and a smooth, rounded flavor to the greens and sauce.
- Broth or gravy
- Supplies savory liquid that the flour thickens and that reduces into a concentrated sauce.
- Vinegar or lemon juice
- Adds acidity that brightens the rich, savory sauce and balances its flavor.
The step that matters
Boil quickly until fairly dry. Boiling off excess liquid concentrates the flavor and lets the flour thicken the sauce properly. If the mixture stays too wet, the sauce will be thin and watery.
Swap the spinach
How well each one fits the dish's main ingredients (pepper, butter, flour, vinegar, bread):
- Shallotfits better
- Capsicumfits better
- Mustardfits about as well
- Spinachthe original
Fit is the average pairing score against pepper, butter, flour, vinegar, bread. Candidates are from the same food group and used in at least 100 recipes.
