Why it works: Carrot and pepper match in chemistry and in kitchens. They rank in the top 6% of all ingredient pairs, and cooks put them together in 14,555 recipes. Both carry 2-isopropyl-3-methoxypyrazine, which smells earthy, pea. The science ↓
Haricot Mutton
Ingredients
Directions
Prepare
Wipe the meat with a damp cloth if necessary.
Divide the meat into chops or trim pieces nicely.
Cut the onions into rings.
Prepare the vegetables by cutting them into small squares, slices, or fillets as desired.
Brown and stew
Heat the dripping in a stew pan.
Fry the meat lightly on both sides.
Fry the onions with the meat.
Remove the dripping from the meat.
Add the vegetables, flour, salt, and pepper. Stir well.
Gradually add the hot water. Stir until it boils.
Simmer for 1 to 1½ hours, or until the meat is tender. Stir often to prevent burning.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Mutton
- Its connective tissue softens during long simmering, making the meat tender.
- Flour
- Thickens the cooking liquid into a smooth, rich gravy as it heats.
- Onions
- Soften and sweeten as they cook, adding depth to the gravy.
- Dripping
- Fat for frying that carries flavour and helps the meat brown.
The step that matters
Frying the meat lightly on both sides. Browning the surface builds savoury flavour through the Maillard reaction. Pieces should be dry and fried in a single layer so they brown rather than steam.
Swap the onion
How well each one fits the dish's main ingredients (mutton, flour, carrot, pepper):

- Leekfits better
- Onionthe original
Fit is the average pairing score against mutton, flour, carrot, pepper. Candidates are from the same food group and used in at least 100 recipes.
