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 ↓
Beef Steak 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
Stew the steak strips with the bone in enough water to cover until partly cooked.
Line a baking dish with pie crust.
Layer and assemble
Layer the meat in the dish, seasoning with salt, pepper, and onion.
Add a layer of sliced potatoes and dot with butter.
Repeat layers of steak and potatoes until the dish is full.
Thicken the broth with brown flour and pour it over the layers.
Cover with a top crust, making a slit in the middle, and brush with beaten egg.
Bake
Bake at 400°F (200°C) until the crust is golden brown.

Butter and flour barely smell alike, yet cooks put them together in 124,287 recipes: they work on texture and structure more than aroma.
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 savory meat that becomes tender during stewing and baking.
- Brown flour
- Thickens the broth so it binds the layers rather than running off.
- Butter
- Adds richness and moisture to the potato layers as it melts.
- Pie crust
- Forms the lining and top that enclose the filling and brown in the oven.
- Egg
- Brushed on top, it helps the crust turn golden and glossy as it bakes.
The step that matters
Thicken the broth before pouring it over the layers. Flour needs heat and liquid to swell and thicken; if the broth is too thin or unevenly thickened, the filling will be runny or pasty once baked.
Swap the onion
How well each one fits the dish's main ingredients (meat, potato, pepper, butter, flour, egg):
- Asparagusfits 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.
