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 ↓
Beef 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 the filling
Preheat the oven to 400°F (200°C).
Fry the sliced onion in beef drippings until soft.
Add flour to the onions and cook until browned.
Layer the onion mixture in a pie dish, followed by the beef.
Season with salt and pepper, and add tomato slices if desired.
Pour in the beef juice and gravy to nearly fill the dish.
Add water or beef stock as needed.
Top and bake
Mash the boiled potatoes with salt and cream or butter until light.
Spread the mashed potatoes over the beef mixture, about 1.5 inches thick.
Brush the top with beaten egg.
Bake in the oven for 30 minutes until browned.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Beef
- Provides the main savory meat filling and rich flavor of the pie.
- All-purpose flour
- Cooked with the onions to brown and thicken the filling.
- Potatoes
- Form the light, soft mashed topping that covers the filling.
- Beef drippings
- Fat that softens the onion and carries savory meat flavor into the filling.
- Egg
- Brushed on top to help the potato crust brown in the oven.
The step that matters
Cooking the flour with the onions until browned. Flour cooked in fat until browned loses its raw taste and later thickens the gravy evenly. Undercooked flour leaves a pasty flavor and can make the filling gluey.
Swap the tomato
The recipe marks tomato as optional. How well each one fits the dish's main ingredients (beef, onion, flour, pepper, potato, cream, egg):
- Chivefits better
- Leekfits better
- Spinachfits better
- Tomatothe original
Fit is the average pairing score against beef, onion, flour, pepper, potato, cream, egg. Candidates are from the same food group and used in at least 100 recipes.
