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
Remove excess water from the cooked greens and chop them slightly.
Make the gravy
In a clean saucepan, heat the greens with butter, salt, and pepper.
Dredge in flour and stir well.
Add broth or gravy and boil quickly until the mixture is fairly dry.
Stir in vinegar or lemon juice and serve hot with fried sippets.

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
- Form the bulk of the dish and carry the flavour of the gravy.
- Flour
- Thickens the liquid and helps the greens bind into a coating-like mixture.
- Butter
- Adds fat and richness, carrying flavour through the greens.
- Broth or gravy
- Supplies the liquid that is reduced to create a savoury, concentrated coating.
- Vinegar or lemon juice
- Adds acidity that brightens the flavour and balances the richness.
The step that matters
Boil quickly until fairly dry. Flour thickens the liquid only as it cooks; boiling hard reduces excess moisture so the greens hold together rather than turning watery. Stopping too early leaves the gravy thin and diluted.
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.
