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 ↓
To Ragout a Knuckle of Veal
6 personsIngredients
Directions
Prepare the meat
Cut the meat from a knuckle of veal into neat slices, season with pepper and salt, and dredge them with flour.
Fry the sliced meat in a little butter until pale brown.
Put the browned meat into a stewpan with the bone, which should be chopped in several places.
Make the gravy
Add the celery, herbs, mace, and carrots to the stewpan.
Pour about 1 pint of hot water over the contents.
Let the mixture simmer very gently for 2 hours over a slow but clear fire.
Take out the slices of meat and carrots.
Strain the liquid and thicken the gravy with a little butter rolled in flour.
Add the remaining ingredients (ketchup, tomato sauce, sherry, lemon juice, celery seed, etc.).
Give the gravy one boil.
Finish and serve
Put the meat and carrots back into the gravy.
Let them heat through.
Serve.
(Optional) Add boiled green peas at the moment of serving.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Veal knuckle meat (in the method)
- Provides the main meat, which browns and becomes tender during the long gentle simmer.
- Flour (in the method)
- Dredges the meat for browning and thickens the gravy with the butter.
- Butter (in the method)
- Browns the meat and forms a roux with flour to thicken the gravy.
- Sherry
- Adds acidity and a rich aromatic flavour to the gravy.
- Tomato sauce
- Adds acidity, colour and savoury depth to the gravy.
The step that matters
Simmer very gently for 2 hours. A vigorous boil toughens meat proteins and can cloud the gravy, while a slow simmer lets collagen soften gradually and keeps the broth clear.
Swap the mace
How well each one fits the dish's main ingredients (celery, ketchup, tomato, sauce, sherry, onion, lemon):
- Thymefits better
- Parsleyfits better
- Tarragonfits better
- Macethe original
Fit is the average pairing score against celery, ketchup, tomato, sauce, sherry, onion, lemon. Candidates are from the same food group and used in at least 100 recipes.
“What each ingredient does” and “The step that matters” were written by Claude from this recipe’s own method and reviewed in samples by CompKitchen.
