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 ↓
Roast Beef Pie with Potato Crttst
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.
Make the beef filling
In a stewpan, combine sliced beef, gravy, butter, onion, pepper, salt, and enough water to create gravy.
Dredge the stew in flour to thicken.
Simmer gently to avoid burning.
Make the potato topping
Boil potatoes until tender.
Mash the potatoes smooth with milk and butter.
Assemble and bake
Preheat the oven to 400°F (200°C).
Transfer the stewed meat to a baking dish.
Layer the mashed potatoes on top.
Brush the potato layer with beaten egg.
Bake in the oven until the top is golden brown.
Serve with tomato sauce or Worcestershire sauce.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Cold roast beef
- Provides the meat that forms the main body of the filling.
- Gravy from the roast
- Supplies moisture and savory flavor to the filling.
- Flour
- Thickens the stewed meat so it holds together rather than running in the dish.
- Potatoes
- Form the mashed topping that covers and seals the filling.
- Egg
- Brushed on top, it promotes browning of the potato crust in the oven.
The step that matters
Simmer gently. Gentle heat keeps the flour-thickened gravy from scorching on the bottom of the pan, while still letting it thicken evenly. Vigorous boiling can burn the starches and meat sugars and make the filling taste bitter.
