Why it works: Ketchup and sauce 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 ↓
An Excellent Hashed Beef or Mutton
Ingredients
Directions
Prepare
Remove skin and outer edges from the meat and cut it into neat slices.
Make the sauce
In a stewpan, combine the meat gravy, water, mushroom ketchup, Harvey Sauce, minced herbs, chopped onion, salt, and cayenne; bring to a boil for 15 minutes.
Mix a little of the liquid with the flour, then stir it into the stewpan and boil for another 10 minutes.
Strain the mixture through a sieve back into the pan, add the meat slices, and keep warm without boiling.
Finish and serve
Just before serving, stir in the tarragon vinegar and arrange croutons around a hot dish.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Flour
- Thickens the liquid into a smooth gravy as it boils.
- Mushroom ketchup
- Adds deep savoury, umami flavour to the gravy.
- Tarragon vinegar
- Adds a bright acidity that lifts the rich gravy when stirred in at the end.
- Onion
- Adds aromatic sweetness and body to the simmered liquid.
The step that matters
Keep the meat warm without boiling. Boiling toughens meat proteins and makes them dry and stringy, so the slices should be held just below a simmer once added.
Swap the onion
How well each one fits the dish's main ingredients (meat, mushroom, ketchup, sauce, flour, tarragon, vinegar):
- Shallotfits better
- Mustardfits better
- Horseradishfits better
- Onionthe original
Fit is the average pairing score against meat, mushroom, ketchup, sauce, flour, tarragon, vinegar. Candidates are from the same food group and used in at least 100 recipes.
