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
The book gives no oven temperature. The 400°F (200°C) in the steps was added when the recipe was transcribed, as a starting point.
Prepare the beef and bones
Cut the fillet of the inside sirloin into small pieces.
Cut the bones into neat pieces, leaving plenty of meat on them.
Score the bones.
Season the bones with salt and pepper.
Place the bones in a tart pan with oiled butter.
Warm the bones in the oven at 400°F (200°C).
Brown the bones on a grill.
Make the stock
In a stewpan, combine meat trimmings, bones, sliced onions, vinegar, and stock.
Boil the mixture slowly for at least an hour.
Strain the mixture.
Skim off the fat.
Make the sauce and serve
Melt butter in a stewpan.
Add flour to the melted butter. Stir for 1-2 minutes.
Gradually add the strained liquid. Stir until it boils.
Add a little ketchup.
Strain the sauce through a fine sieve.
Return the beef to the sauce. Keep the sauce hot without boiling.
Season if needed.
Serve with the broiled bones around the dish.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Fillet of inside sirloin beef
- Provides the main meat, tender and juicy when kept from overcooking.
- Beef bones
- Release gelatin and flavour into the stock, and brown for savoury taste.
- Large onions
- Add sweetness and aroma to the stock as it simmers.
- Flour
- Thickens the butter and liquid into a smooth, body-giving sauce.
- Beef stock
- Forms the liquid base that carries the flavour of the sauce.
- Butter
- Adds richness and fat that carries flavour and gives a silky mouthfeel.
The step that matters
Gradually add the strained liquid to the flour and butter. Adding liquid slowly while stirring keeps flour lumps from forming, so the roux blends smoothly and thickens evenly as it boils.
