Why it works: Pepper and parsley match in chemistry and in kitchens. They rank in the top 2% of all ingredient pairs, and cooks put them together in 34,122 recipes. Both carry 4'-methylacetophenone, which smells bitter almond. The science ↓
Roast Mutton
Ingredients
Directions
The book says “a very hot oven”. The 400°F in the steps is the modern equivalent, not the book's own figure.
Prepare
Rub the leg of mutton or lamb with coarse sea salt and black pepper.
Place it in a baking pan with a little water.
Roast and serve
Set in a very hot oven (400°F / 200°C) and baste frequently.
When done, add minced parsley to the gravy.
Cover the roast with grated cracker before serving.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Leg of mutton or lamb
- Provides the main meat, which becomes tender and juicy as it roasts.
- Grated cracker
- Forms a crumb coating on the roast, adding a light crisp texture.
The step that matters
Basting frequently in a very hot oven. Regular basting moistens the surface of the meat as it roasts, helping keep it from drying out while the outside browns.
Swap the parsley
How well each one fits the dish's main ingredients (mutton, pepper):
- Parsleythe original
- Turmericfits about as well
- Marjoramfits less well
- Celeryfits less well
Fit is the average pairing score against mutton, pepper. Candidates are from the same food group and used in at least 100 recipes.
