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
Ingredients
Directions
Make the gravy
Combine beef trimmings, bones, sliced onions, vinegar, and stock in a saucepan. Simmer for 1 hour.
Strain the mixture and skim off the fat.
Thicken and finish
Melt the butter in a clean saucepan. Stir in the flour and cook for 2–3 minutes.
Add the strained gravy to the butter‑flour mixture. Stir until it boils.
Add a little catsup and the sliced beef. Simmer until heated through, but do not boil.
Serve the bones
If serving the bones, score and season them with pepper and salt. Place them in a tin pan with small bits of butter.
Heat the bones in a Dutch oven, then broil on a gridiron until browned.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Beef
- Gives the dish its meaty flavour and forms the sliced meat served in the gravy.
- Onions
- Add sweetness and savoury depth to the stock as it simmers.
- Vinegar
- Adds acidity that brightens the flavour of the gravy.
- Flour
- Thickens the butter and gravy mixture so it coats the beef.
- Butter
- Adds richness and fat that carries flavour and helps form the thickened base.
The step that matters
Keep the beef below a boil. Simmering only gently keeps thin slices of beef tender and stops them toughening, while boiling would make the meat firm and dry.

Fit is the average pairing score against beef, vinegar, butter, flour, pepper. Candidates are from the same food group and used in at least 100 recipes.
