Why it works: Potato and onion 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 ↓
Meat and Potato Pie
Ingredients
Directions
The book says “a moderate oven”. The 350°F (175°C) in the steps is the modern equivalent, not the book's own figure.
Prepare
Cut the mutton into small thin slices.
Parboil and slice the potatoes and onions.
Layer and bake
Line the bottom of a pie dish with potato.
Cover with a layer of mutton and a few slices of onion, seasoning with salt and pepper.
Repeat layers until all ingredients are used, finishing with a layer of potato.
Pour in the gravy.
Cover with greased paper and bake at 350°F (175°C) for about 1.5 hours.
Remove the paper 30 minutes before serving to allow the surface to brown.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Mutton
- Forms the meaty filling and provides most of the savoury flavour as it cooks in the layers.
- Potatoes
- Parboiled slices form the base and top layers, giving body and a soft, starchy texture.
- Onions
- Sliced between the layers, they add sweetness and aroma as they soften during baking.
- Gravy
- Poured in to moisten the layers, keeping the mutton and potato from drying out in the oven.
The step that matters
Remove the paper 30 minutes before serving. Covered baking traps steam and keeps the surface pale. Uncovering for the final 30 minutes lets dry heat evaporate surface moisture and brown the top, so it should not be skipped.
Swap the onion
How well each one fits the dish's main ingredients (mutton, potato, pepper):
- Carrotfits better
- Capsicumfits better
- Tomatofits about as well
- Onionthe original
Fit is the average pairing score against mutton, potato, pepper. Candidates are from the same food group and used in at least 100 recipes.
