Why it works: Pepper and lemon 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 ↓
Poultry, Hashed
Ingredients
Directions
Prepare the sauce
Combine the fowl trimmings with 1 pint of stock in a stewpan and let them stew.
Melt 1 ounce of dripping in a pan and fry the chopped onion until soft.
Cook the hash
Add the fowl pieces to the pan, season with salt and pepper, and let them brown slightly.
Mix ½ ounce of butter and ½ ounce of flour together, then add to the poultry.
Gradually pour in the stock and let everything simmer gently for about 30 minutes.
If the sauce is too thick, moisten it with a little more stock or water and bring to a boil.
Finish and serve
Remove the fowl pieces and place them on a hot dish.
Add a squeeze of lemon, skim off any fat, and strain the sauce over the dish.
Serve with slices of toast around the dish.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Cold fowl or duck
- Forms the main body of the dish and is gently warmed through in the sauce.
- Onion
- Softens during frying and adds savoury sweetness to the base of the sauce.
- Butter and flour
- Flour mixed with butter forms a roux that thickens the sauce as it simmers.
- Stock
- Forms the liquid of the sauce, carrying flavour and setting its consistency as it reduces.
The step that matters
Adding the butter and flour mixture. Flour must be mixed fully into the fat and cooked briefly before liquid is added; otherwise it stays lumpy or tastes raw. Gradual stock addition keeps the sauce smooth.
Swap the onion
How well each one fits the dish's main ingredients (pepper, butter, flour, lemon):
- Shallotfits better
- Arrowrootfits better
- Okrafits better
- Onionthe original
Fit is the average pairing score against pepper, butter, flour, lemon. Candidates are from the same food group and used in at least 100 recipes.
