Why it works: Sauce and ketchup match in chemistry and in kitchens. They rank in the top 1% of all ingredient pairs, and cooks put them together in 1,099 recipes. Both carry ethanol, which smells alcoholic, ethereal. The science ↓
Hashed Beef and Broiled Bones
Ingredients
Directions
Prepare
Cut leftover roast beef into neat pieces.
Shorten the broiling bones, leaving some meat on them, and score them.
Season the bones with pepper and salt, then broil over a clear fire.
Make the stock
In a saucepan, combine the trimmings from the bones and meat with 2 onions and 1 pint of water.
Boil slowly for 1 hour, ensuring it doesn't boil fast.
Strain the mixture into a basin.
Make the hash
Sprinkle ½ tablespoon of flour over the meat and mix well.
Add the strained liquid to the meat in the saucepan and toss to combine.
Heat just enough to remove the rawness of the flour.
Stir in 1 tablespoon of Worcestershire sauce, 1 tablespoon of mushroom ketchup, and chopped gherkins.
Season with a little pepper and salt.
Serve the hash on a dish and place the broiled bones on top.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Leftover roast beef
- Provides the main meat of the hash, bulk and savoury flavour.
- Broiling bones
- Broiling browns the bones and adds roasted flavour to the stock and dish.
- Onions
- Add sweetness and savoury depth to the stock that flavours the hash.
- Flour
- Thickens the strained liquid into a light gravy that coats the meat.
- Worcestershire sauce
- Adds tangy, savoury depth that rounds out the gravy.
The step that matters
Heat just enough to remove the rawness of the flour. Flour must be heated long enough to cook out its raw, starchy taste, but over-heating can make the gravy thick and pasty or cause it to scorch. Gentle heat while stirring keeps it smooth.
Swap the onion
How well each one fits the dish's main ingredients (beef, flour, sauce, mushroom, ketchup, pepper):
- Shallotfits better
- Capsicumfits better
- Horseradishfits better
- Onionthe original
Fit is the average pairing score against beef, flour, sauce, mushroom, ketchup, pepper. Candidates are from the same food group and used in at least 100 recipes.
