Why it works: Parsley and pepper 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 ↓
Mutton and Potato Pie
Ingredients
Directions
The book says “a moderately hot oven”. The 400°F (200°C) in the steps is the modern equivalent, not the book's own figure.
Prepare the meat
Saw the rib bones across, remove the short ends, fold the flap under, and bind securely.
Place the meat in a pot with enough boiling stock (or water and flavoring vegetables) to barely cover it, and simmer gently for about 1 hour.
Drain the meat well.
Coat and bake
Beat the egg, then add the parsley, herbs, and a good seasoning of salt and pepper, and coat the meat thickly with this mixture.
Cover the meat lightly with bread crumbs and bake in a 400°F (200°C) oven until well browned, basting frequently with hot fat.
Make the sauce
In a separate pan, heat the butter, add the flour, stir and cook slowly until well browned.
Add 1 pint of boiling stock from the larger pot, stir until boiling, season to taste, and simmer gently until required.

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
- Provides the main meat, which becomes tender through long gentle simmering.
- Egg
- Binds the parsley and herb seasoning so it adheres to the meat.
- Bread crumbs
- Form a crisp, browned crust over the coated meat in the oven.
- Butter
- Enriches the sauce and carries flavor when cooked with the flour.
- Flour
- Cooked with the butter to form a roux that thickens the stock sauce.
The step that matters
Browning the butter and flour. Cooking the roux slowly until well browned develops nutty flavor and color; if rushed or left too pale, the sauce tastes raw and looks washed out.
Swap the parsley
How well each one fits the dish's main ingredients (mutton, butter, flour, egg, bread, pepper):
- Parsleythe original
- Nutmegfits about as well
- Capersfits less well
- Turmericfits less well
Fit is the average pairing score against mutton, butter, flour, egg, bread, pepper. Candidates are from the same food group and used in at least 100 recipes.
“What each ingredient does” and “The step that matters” were written by Claude from this recipe’s own method and reviewed in samples by CompKitchen.
