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 ↓
Beefsteak and Potato Pie
Ingredients
Directions
The book says “a hot oven”. The 350°F (175°C) in the steps is the modern equivalent, not the book's own figure.
Prepare
Peel the potatoes and cut them into thin slices about 2 inches long and 1 inch wide.
Mix the flour, salt, and pepper on a plate. Dip the slices of beef in the mixture and roll them up tightly.
Assemble
Line the bottom of a pie dish with potato slices, sprinkle with salt and pepper, cover with rolls of beef, and add a little onion sparingly.
Repeat the layers until the dish is full, then add boiling water to fill three-quarters of the dish.
Bake and serve
Cover with pastry and bake for 2 hours at 350°F (175°C).
Before serving, pour a little hot beef gravy or hot water seasoned with salt and pepper through the hole in the top.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Beefsteak
- Provides the savoury meat filling, which becomes tender during the long, covered bake.
- Potatoes
- Form the layers of the filling and soften as they cook, adding body to the pie.
- Flour
- Coats the beef and thickens the cooking juices into a light gravy.
- Onion
- Adds aroma and mild sweetness to the meat and potato layers.
The step that matters
Covering and baking the full 2 hours. The beef is cooked inside a sealed pastry crust with liquid, so it needs the full long bake for its tough connective tissue to break down. Cutting the time short leaves the meat chewy and the juices underdeveloped.
Swap the onion
How well each one fits the dish's main ingredients (potato, flour, pepper):
- Chivefits better
- Spinachfits better
- Okrafits better
- Onionthe original
Fit is the average pairing score against potato, flour, pepper. Candidates are from the same food group and used in at least 100 recipes.
