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 ↓
Haricot of Mutton
Ingredients
Directions
Prepare and brown
Cut the mutton chops thin from the neck or fore‑loin, removing the skin and fat.
Fry the chops in fat until light brown, then remove them from the pan.
Fry the sliced onion in the same pan.
Simmer
Pour away the fat, then return the chops to the pan with half the grated carrot, pepper, salt, and hot water.
Cover tightly and simmer slowly for two hours.
Thicken and serve
Thicken the mixture with flour mixed with ketchup and Worcestershire sauce.
Boil for a few minutes and skim off any fat.
Garnish with boiled carrot and turnip cut into shapes.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Mutton chops
- Provide the meat, which becomes tender during slow simmering.
- Flour
- Thickens the cooking liquid into a stew-like sauce.
- Onion
- Adds savoury depth when fried before the stew is simmered.
- Fat or dripping
- Browns the chops and carries flavour from the start of cooking.
- Carrot
- Adds natural sweetness and body to the stewing liquid.
The step that matters
Simmering the chops gently with a tight cover. A slow, covered simmer breaks down the connective tissue in the mutton so it becomes tender. Boiling hard toughens the meat and can make the liquid cloudy or greasy, so keep it at a gentle simmer.
Swap the onion
How well each one fits the dish's main ingredients (mutton, flour, ketchup, sauce, carrot, turnip, pepper):
- Leekfits better
- Shallotfits better
- Parsnipfits better
- Onionthe original
Fit is the average pairing score against mutton, flour, ketchup, sauce, carrot, turnip, pepper. Candidates are from the same food group and used in at least 100 recipes.
