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 gives no oven temperature. The 400°F (200°C) in the steps was added when the recipe was transcribed, as a starting point.
Prepare
Boil and mash the potatoes, then line a buttered pie dish with them.
Boil and slice the onions.
Layer and bake
Layer slices of meat in the dish, followed by a layer of onions, seasoning both layers.
Add another layer of potatoes and repeat the layers until the dish is full.
Dot the top layer of potatoes with small pieces of butter.
Bake at 400°F (200°C) for 30 minutes.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Potatoes
- Form the bulk of the layers and become soft and starchy when mashed.
- Mutton
- Provides the savoury meat filling that the layers are built around.
- Onions
- Add sweetness and aroma as they soften between the meat and potato layers.
- Butter
- Adds richness and fat to the top layer of potatoes.
- Gravy
- Supplies moisture so the layers stay juicy during baking.
The step that matters
Dot the top layer of potatoes with small pieces of butter.. Butter on the surface carries fat into the top potatoes, helping them brown and giving a richer finish. Spreading it evenly keeps the browning consistent across the pie.
