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 and Broiled Bones
Ingredients
Directions
Prepare
Cut the beef fillet into collop-sized pieces and prepare the bones.
Score the bones and season with salt and pepper.
Broil the bones over a clear fire for about 5 minutes.
Place the hash on a dish and top with the broiled bones.
Make the sauce
In a stew pan, combine beef trimmings, bones, sliced onions, vinegar, and beef stock.
Bring to a boil and simmer for 1 hour, then strain and skim the fat.
Melt butter in a stew pan, add flour to absorb the butter, and stir in the strained liquid.
Strain again through a fine sieve and return to the pan.
Finish
Add walnut ketchup and sliced gherkins, then stir in the meat and heat without boiling.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Sirloin beef fillet
- Provides the meaty base of the hash, with tenderness depending on gentle heating.
- Beef stock
- Supplies the liquid and savoury body that forms the sauce.
- Onions
- Soften and sweeten as they cook, adding depth to the sauce.
- Butter
- Adds richness and fat that carries flavour and gives a smooth mouthfeel.
- Flour
- Absorbs the butter and thickens the liquid through starch.
- Vinegar
- Adds acidity that brightens the sauce and balances the richness.
The step that matters
Heat the meat without boiling. Once the meat goes into the sauce, boiling can toughen the protein and make it dry and stringy. Gentle heating keeps it tender and the sauce smooth.
