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 Mutton
Ingredients
Directions
Prepare
Cut the cold mutton into evenly sized slices, removing all fat, skin, and bone.
Melt the butter in a large saucepan over medium heat.
Make the sauce
Add the minced eschalots and flour, stirring for 5 minutes until browned.
Add the stock, salt, whole pepper, clove, allspice, bouquet garni, walnut ketchup, and tomato sauce. Stir until boiling.
Boil for 5 minutes, then strain the sauce into another saucepan and let it cool.
Finish and serve
Once cooled, add the pieces of mutton to the sauce.
Heat the saucepan over low heat, shaking occasionally, but do not let it boil.
Serve the warmed mutton with fried bread slices.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Cold mutton
- Provides the meat, which is gently warmed in the sauce so it stays tender.
- Eschalots
- Browned in butter, they add savoury depth and sweetness to the sauce.
- Butter
- Carries the browning of the eschalots and adds richness to the sauce.
- Stock
- Forms the liquid base of the sauce, adding body and savoury flavour.
- Tomato sauce
- Adds acidity and colour to the sauce.
- Walnut ketchup
- Adds a deep, savoury, salty note to the sauce.
The step that matters
Heat the mutton gently without boiling. Boiling toughens meat proteins and squeezes out moisture, so the mutton turns dry and chewy. Gentle, low heat warms it through while keeping it tender.
Swap the walnut
How well each one fits the dish's main ingredients (mutton, tomato, sauce, butter, ketchup, pepper, clove):
- Beansfits better
- Walnutthe original
- Peasfits about as well
- Chestnutfits about as well
Fit is the average pairing score against mutton, tomato, sauce, butter, ketchup, pepper, clove. Candidates are from the same food group and used in at least 100 recipes.
