Why it works: Peppermint and pepper match in chemistry and in kitchens. They rank in the top 7% of all ingredient pairs, and cooks put them together in 1,517 recipes. Both carry methyl cinnamate, which smells strawberry. The science ↓
Leg of Mutton, English Style
Ingredients
Directions
Prepare the meat
Remove excess fat from the leg of mutton and wash it well.
Pound the meat, then season with salt and pepper.
Roast
Place in the oven with ½ pint of boiling water and add 1 tablespoon of butter.
Roast for 1½ hours, basting frequently for rare, or 2 to 2½ hours for well done.
Serve
Wash and finely chop the peppermint, then mix with vinegar and sugar to serve with the meat.
For gravy, pour off fat, add 1½ tablespoons of flour, brown it, then stir in 1 cup of water and ¼ cup of cream, boil, season with salt, strain, and serve.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Leg of mutton
- Forms the main body of the dish, and its fat and lean meat set the texture and flavour of the roast.
- Butter
- Adds richness and fat to the roast, helping browning and a moist surface.
- Vinegar
- Adds acidity that cuts through the richness of the meat and the mint sauce.
- Flour (in the method)
- Thickens the gravy as it browns in the pan fat.
- Cream (in the method)
- Adds richness and body to the gravy.
- Sugar
- Balances the sharpness of the vinegar in the mint sauce.
The step that matters
Roasting time for doneness. Rare and well-done results depend on the cooking time, so the cook must check the meat early for rare. Basting keeps the surface moist while the meat roasts, so the outside does not dry out before the centre is cooked.
Swap the peppermint
How well each one fits the dish's main ingredients (mutton, butter, pepper, vinegar, sugar):
- Cinnamonfits better
- Parsleyfits better
- Tarragonfits about as well
- Peppermintthe original
Fit is the average pairing score against mutton, butter, pepper, vinegar, sugar. Candidates are from the same food group and used in at least 100 recipes.
