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
Stew the steak strips with the bone in enough water to cover them until partly cooked.
Line a baking dish with pie paste.
Layer the meat in the dish, seasoning with salt, pepper, and onion.
Add a layer of sliced potatoes and dot with butter.
Continue layering steak and potatoes until the dish is full.
Assemble and bake
Thicken the broth with brown flour and pour it over the layers.
Cover with a top crust, making a slit in the middle.
Brush the crust with beaten egg.
Bake at 400°F (200°C) until golden 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 meat that becomes tender during stewing and forms the main body of the pie.
- Sliced potatoes
- Form starchy layers that absorb juices and add body to the filling.
- Butter
- Adds richness and fat that carries flavour through the layers.
- Brown flour
- Thickens the broth so it clings to the meat and potatoes rather than running off.
- Beaten egg
- Brushes the top crust to promote browning and a glossy golden finish.
The step that matters
Stewing the steak until partly cooked. Flank and rump steak are lean and tough, and they need enough gentle, moist heat to soften the connective tissue. Stewing only partly cooks the meat, so it finishes tenderly in the oven rather than drying out.
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.
“What each ingredient does” and “The step that matters” were written by Claude from this recipe’s own method and reviewed in samples by CompKitchen.
