Why it works: Parsley and onion are a kitchen classic. They rank in the top 9% of all ingredient pairs, and cooks put them together in 25,843 recipes. Both carry 2,4-decadienal, which smells seaweed. The science ↓
Potted Fowl
Ingredients
Directions
Prepare the stock
Remove all the meat from the cold roasted or boiled fowl using a fork and place it in a stewpan.
In another pan, combine the small beaten bones with ½ pint of water, seasoning, parsley, and onion if using.
Simmer until the liquid is reduced by half, then strain it and add to the meat.
Finish the mixture
Mix the flour and butter together, then add to the stewpan along with the salt and sugar.
Boil for 2 minutes, adding more water or broth if the mixture is too thick.

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
- Flour
- Thickens the liquid into a smooth, spreadable mixture as it cooks.
- Butter
- Adds richness and a smooth texture, and helps the flour blend in.
- Fowl
- Supplies the meat that forms the body of the potted dish.
The step that matters
Boiling after adding the flour and butter. Flour thickens only when it boils and its starch swells in the hot liquid. Boiling for the full time cooks out the raw flour taste and sets the texture. Adding liquid if it gets too thick keeps it spreadable.
Swap the onion
The recipe marks onion as optional. How well each one fits the dish's main ingredients (meat, parsley, flour, butter, sugar):
- Shallotfits better
- Leekfits better
- Chivefits better
- Onionthe original
Fit is the average pairing score against meat, parsley, flour, butter, sugar. Candidates are from the same food group and used in at least 100 recipes.
