Why it works: Pepper and carrot 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 ↓
Leg of Mutton with Carrots
Ingredients
Directions
Brown the mutton
Lard the leg of mutton and place it in a stew pan with butter.
Heat over medium for 5-10 minutes, turning to brown all sides.
Remove the mutton and mix flour into the butter in the pan.
Add broth or boiling water and let simmer, stirring often.
Simmer and serve
Return the mutton to the pan and add more broth or water as needed.
Season with salt, pepper, and herbs.
Slowly boil for 2 hours.
Add the browned carrots and boil for another hour before serving.

Butter and flour barely smell alike, yet cooks put them together in 124,287 recipes: they work on texture and structure more than aroma.
Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Mutton
- Long slow simmering turns the tough meat tender and gives the stew its savoury body.
- Butter
- Carries the browning of the meat and forms the base that flour thickens.
- Flour
- Thickens the cooking liquid into a body-rich stew sauce when mixed into the butter.
- Broth
- Supplies the liquid that cooks the meat and becomes the stew's savoury sauce.
- Carrots
- Add natural sweetness and a softened texture as they finish cooking in the stew.
The step that matters
Brown the mutton on all sides. Browning builds deep flavour through the Maillard reaction, which only happens on dry, hot surfaces. Crowding or steaming the meat leaves the stew tasting flat and grey.

Fit is the average pairing score against mutton, butter, flour, pepper. Candidates are from the same food group and used in at least 100 recipes.
