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 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
Cut the steak into strips and stew with the bone in enough water to cover until partly cooked.
Line a baking dish with pie paste.
Layer and thicken
Layer the meat with salt, pepper, and onion, then add a layer of sliced potatoes with butter dots.
Continue layering steak and potatoes until the dish is full.
Thicken the broth with brown flour and add it to the dish.
Bake
Cover with a top crust, make a slit in the middle, brush with beaten egg, and bake at 400°F (200°C) until brown.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Rump or flank steak
- Provides the main meat, which becomes tender through partial stewing and baking.
- Potatoes
- Add body and starch to the filling, soaking up some of the savoury broth.
- Brown flour
- Thickens the broth so it sets into a rich gravy rather than running out of the pie.
- Pie paste
- Forms the crust that encloses the filling and browns during baking.
- Beaten egg
- Brushed on the top crust to promote even browning and a glossy finish.
The step that matters
Thicken the broth before adding it to the dish. Flour needs to be cooked in liquid to swell and thicken it; if the broth is too thin, it will run out of the pie and leave the filling watery.
Swap the onion
How well each one fits the dish's main ingredients (meat, potato, pepper, butter, flour, egg):
- Asparagusfits better
- Chivefits better
- Shallotfits better
- Onionthe original
Fit is the average pairing score against meat, potato, pepper, butter, flour, egg. Candidates are from the same food group and used in at least 100 recipes.
