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 ↓
Mutton and Potato 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
Cut the mutton into small thin slices.
Parboil and slice the potatoes and onions.
Assemble the pie
Line the bottom of a pie dish with a layer of potatoes.
Add a layer of mutton and a few slices of onion, seasoning with salt and pepper.
Repeat the layers until all ingredients are used, finishing with a layer of potatoes.
Pour in the gravy and cover with greased paper.
Bake and serve
Bake for about 1 hour at 350°F (175°C).
Remove the paper 15 minutes before serving to allow the potatoes to brown.

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 filling, cooked gently in the oven until tender.
- Potatoes
- Form the layers that soften during baking and then brown on top when the paper is removed.
- Gravy
- Adds moisture so the layers stay juicy as the pie bakes.
- Onions
- Add savoury flavour that mellows and sweetens as they cook among the meat and potatoes.
The step that matters
Removing the paper before serving. The paper traps steam so the meat and potatoes cook through without drying. Removing it for the final 15 minutes lets surface starch dry and brown, which is why timing matters.
