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
Sear the mutton
Heat the butter in a stew-pan over medium heat.
Sear the leg of mutton on all sides for 5–10 minutes.
Remove the mutton and mix the butter with flour in the pan.
Add the broth or boiling water and simmer, stirring constantly.
Stew
Return the mutton to the pan, season with salt and pepper, and add the herbs.
Boil slowly for 3 hours.
In a separate pan, brown the carrot pieces in butter.
Add the browned carrots to the mutton and boil for an additional 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
- Leg of mutton
- Provides the main meat, which becomes tender through long, slow simmering.
- Butter
- Adds fat and richness, and browns the meat and carrots for flavour.
- Flour
- Thickens the cooking liquid into a stew sauce when cooked with the butter.
- Broth or boiling water
- Forms the cooking liquid that moistens the meat and carries flavour through the stew.
- Carrot
- Adds sweetness and colour, and softens during the long simmer.
The step that matters
Adding the broth to the butter and flour. Stirring constantly while the liquid is added keeps the flour smooth, so it thickens the sauce evenly without lumps.

- Carrotthe original
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.
