Why it works: Onion and potato are a kitchen classic. They rank in the top 3% of all ingredient pairs, and cooks put them together in 9,023 recipes. Both carry 2-isopropyl-3-methoxypyrazine, which smells earthy, pea. The science ↓
Mutton or Veal Pie
Ingredients
Directions
The book gives no oven temperature. The 400°F (200°C) in the steps was added when the recipe was transcribed, as a starting point. The book gives no cooking times either; the times in the steps were added in transcription, so check for doneness rather than trusting the clock.
Prepare
Preheat the oven to 400°F (200°C).
Trim the fat from the mutton and season the chops with salt.
Place the chops in a pie dish with water and mushroom ketchup.
Bake the pie
Cover the pie with pie crust.
Bake for about 30 minutes.
Finish the gravy
Lift the crust with a knife.
Pour out the gravy.
Let the gravy stand and skim off the fat.
Add more seasoning to the gravy, if desired.
Bring the gravy to a boil.
Pour the gravy back into the pie.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Mutton
- Meat that becomes tender and rich-flavoured as it cooks slowly in the covered pie.
- Mushroom ketchup
- Adds concentrated mushroom flavour that deepens the savoury taste of the gravy.
- Pie crust
- Seals the pie so the chops cook gently in their own juices and gravy.
The step that matters
Skimming the fat from the gravy. Fat from the meat rises and collects on the surface of the gravy as it stands. Skimming it before reboiling and returning the gravy to the pie keeps the sauce from tasting greasy.
Swap the potato
How well each one fits the dish's main ingredients (mutton, mushroom, ketchup, onion):
- Shallotfits better
- Leekfits better
- Capsicumfits about as well
- Potatothe original
Fit is the average pairing score against mutton, mushroom, ketchup, onion. Candidates are from the same food group and used in at least 100 recipes.
