Why it works: Bread and butter are a kitchen classic. They rank in the top 7% of all ingredient pairs, and cooks put them together in 27,232 recipes. Both carry delta-decalactone, which smells sweet, creamy. The science ↓
Gravy Made Without Meat for Fowls
Ingredients
Directions
Prepare
Thoroughly wash the feet of the fowls and cut them and the neck into small pieces.
Put the feet, neck, bread, onion, herbs, seasoning, livers, and gizzards into a pot.
Simmer and finish
Pour the water over the mixture and simmer gently for 1 hour.
Remove the liver, pound it, and strain the liquid into it.
Add a thickening of butter and flour, and stir in the ketchup.
Boil it up and serve.

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
- Fowl necks, feet, livers, and gizzards
- Provide the main meaty flavor and body of the gravy as they simmer.
- Butter and flour thickening
- Thickens the liquid into a smooth, lightly coated gravy.
- Toasted bread
- Adds body and helps soften and thicken the simmered liquid.
- Onion
- Adds savory sweetness and aroma to the broth.
The step that matters
Add the thickening and boil it up. Flour needs to be fully stirred in and brought to a boil so its starch swells and thickens the gravy evenly and loses its raw floury taste. Stirring while adding prevents lumps.
Swap the onion
How well each one fits the dish's main ingredients (liver, bread, pepper, butter, flour, ketchup):
- Shallotfits better
- Capsicumfits better
- Chivefits about as well
- Onionthe original
Fit is the average pairing score against liver, bread, pepper, butter, flour, ketchup. Candidates are from the same food group and used in at least 100 recipes.
