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
In a saucepan, combine the fowl trimmings, shallots, lemon peel, mace, ham, and stock.
Simmer for 30 minutes, then strain the mixture.
In a clean saucepan, melt a bit of butter. Once melted, stir in enough flour to absorb the butter, mixing continuously.
Add the strained gravy and bring to a boil for 1 minute.
Finish the hash
Add the fowl, then season with pepper, salt, and a dust of sugar.
Before serving, squeeze in a little lemon juice.

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
- Cold roasted fowl
- Provides the main body of the hash as its meat.
- Lean ham
- Adds savoury, salty depth to the stock that flavours the gravy.
- Butter
- Fat that is cooked with flour to form a roux, thickening the gravy.
- Flour
- Absorbs the melted butter to form a roux that thickens the gravy.
- Stock
- Liquid base of the gravy, carrying the flavour of the aromatics.
The step that matters
Stirring the flour into the butter. The flour must be stirred continuously as it absorbs the melted butter, so it cooks evenly without lumps or scorching. Properly mixed, the roux thickens the gravy smoothly.
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.
