Why it works: Butter and flour are a kitchen classic. They rank in the top 12% of all ingredient pairs, and cooks put them together in 124,287 recipes. Both carry isobutyraldehyde, which smells malty, green. The science ↓

Ingredients
Directions
Prepare the greens
Lift the cooked greens out and press the water from them.
Chop the greens slightly and heat them in a clean saucepan with pepper, coarse sea salt, and butter.
Thicken and serve
Dredge in a little flour and stir well.
Add the broth or gravy and boil quickly until the mixture is fairly dry.
Stir in the vinegar or lemon juice and serve hot with fried sippets around them.

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
- Cooked greens
- Form the main body of the dish, with their texture softened by cooking.
- Flour
- Thickens the cooking liquid so the greens cling together rather than sitting in liquid.
- Broth or gravy
- Adds savory liquid and flavor that reduces to coat the greens.
- Vinegar or lemon juice
- Adds acidity that brightens the rich, savory flavors.
The step that matters
Boil quickly until fairly dry. Fast boiling evaporates the excess liquid so the flour-thickened broth becomes a coating rather than a soup. Boiling too gently leaves the greens watery and dilutes the flavor.
