Why it works: Beef and onion are a kitchen classic. They rank in the top 7% of all ingredient pairs, and cooks put them together in 17,092 recipes. Both carry 2-isopropyl-3-methoxypyrazine, which smells earthy, pea. The science ↓
Hashed Beef or Mutton
Ingredients
Directions
Prepare the meat
Cut the cooked meat into thin slices and season with pepper and coarse sea salt.
Remove skin, bones, and gristle from the meat.
Make the gravy
Melt a bit of butter in a stew-pan.
Add a little flour to the butter.
Add a tablespoon of broth or water.
Slice a couple of onions and brown them lightly in the stew-pan.
Add the bones and unwanted meat pieces to the onions.
Include a pickled onion or gherkin and a couple of sprigs of sweet herbs.
Pour in enough water to cover and let it stew until a good gravy forms.
Strain the gravy and season with ketchup, tomato sauce, or vinegar.
Finish and serve
Pour the gravy over the sliced meat in the stew-pan and simmer just to warm the meat through.
Serve with toasted bread.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Cooked beef or mutton
- Provides the main body of the dish, warmed gently so it stays tender in the gravy.
- Butter
- Carries the flavour of the pan and enriches the gravy with fat.
- Flour
- Added to the butter to start thickening the gravy.
- Onions
- Browned lightly to add sweetness and depth of flavour to the gravy.
- Ketchup or tomato sauce or vinegar
- Adds acidity and tang that brightens the rich gravy.
The step that matters
Letting the gravy stew until it forms. Simmering the bones, onions and herbs in water slowly extracts gelatin and flavour; too short a stew gives a thin, weak gravy, while boiling hard can make the meat tough.
Swap the onion
How well each one fits the dish's main ingredients (beef, pepper, butter, flour, ketchup, bread):
- Capsicumfits better
- Shallotfits about as well
- Leekfits about as well
- Onionthe original
Fit is the average pairing score against beef, pepper, butter, flour, ketchup, bread. Candidates are from the same food group and used in at least 100 recipes.
