Why it works: Lemon and pepper match in chemistry and in kitchens. They rank in the top 3% of all ingredient pairs, and cooks put them together in 27,047 recipes. Both carry trans-2-nonenal, which smells cardboard, fatty. The science ↓
Hashed Fowl
Ingredients
Directions
Make the gravy
Cut the cold roasted fowl into pieces as for a fricassee.
Put the trimmings into a saucepan with shallots, lemon peel, mace, ham, and stock.
Simmer for half an hour, then strain the mixture.
Finish the hash
Melt butter in a saucepan, then add enough flour to dry it up while stirring continuously.
Add the strained gravy and let it boil for one minute.
Add the fowl pieces, then season with pepper, salt, and a dust of sugar.
Before serving, squeeze in a little lemon juice.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Cold roasted fowl
- Forms the bulk of the hash and supplies the meat that is gently reheated in the gravy.
- Butter
- Fat that cooks with the flour to form a roux, enriching the gravy.
- Flour
- Thickens the gravy as it cooks with the butter, giving the sauce body.
- Lean ham
- Adds savoury, salty depth to the stock used for the gravy.
- Shallots
- Add mild aromatic sweetness to the stock as it simmers.
- Stock
- Forms the liquid base of the gravy that coats the fowl.
The step that matters
Adding the flour to the butter. Flour must be stirred in continuously so it cooks evenly with the butter; if it is added in lumps or left unstirred, the gravy becomes grainy and lumpy instead of smooth.
Swap the mace
How well each one fits the dish's main ingredients (shallot, lemon, ham, butter, flour, pepper, sugar):
- Capersfits better
- Parsleyfits better
- Tarragonfits better
- Macethe original
Fit is the average pairing score against shallot, lemon, ham, butter, flour, pepper, sugar. Candidates are from the same food group and used in at least 100 recipes.
