Why it works: Pepper and onion are a kitchen classic. They rank in the top 11% of all ingredient pairs, and cooks put them together in 68,474 recipes. Both carry 2-isopropyl-3-methoxypyrazine, which smells earthy, pea. The science ↓
Mutton Pie
Ingredients
Directions
The book gives no oven temperature. The 350°F (175°C) in the steps was added when the recipe was transcribed, as a starting point.
Prepare the gravy
Remove the bones from the mutton and place them in 1 pint of water.
Cook the bones in water for 30 minutes.
Assemble the pie
Cut the mutton and kidneys into small pieces.
Mix the meat with flour, salt, pepper, and minced onion.
Place the mixture into a deep pie dish with the gravy from the bones.
Cover with pastry.
Bake and serve
Bake at 350°F (175°C) for 1.5 hours.
Serve hot.

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 and rich flavour that the pie is built around.
- Kidneys
- Add a deeper, more savoury meaty flavour to the filling.
- Flour
- Thickens the juices from the meat into a gravy that holds the filling together.
- Pastry
- Forms the covering that seals in the filling and browns in the oven.
The step that matters
Bake at 350°F (175°C) for 1.5 hours. The meat must cook through slowly while the pastry browns evenly. Long, moderate heat tenderises tough cuts like mutton and lets the flour-thickened juices set into a gravy rather than leaking out.
Swap the onion
How well each one fits the dish's main ingredients (mutton, flour, pepper):
- Turnipfits better
- Shallotfits better
- Spinachfits better
- Onionthe original
Fit is the average pairing score against mutton, flour, pepper. Candidates are from the same food group and used in at least 100 recipes.
