Why it works: Potato and beef are a kitchen classic. They rank in the top 8% of all ingredient pairs, and cooks put them together in 2,052 recipes. Both carry sotolon, which smells curry, maple. The science ↓
Beef Hash
Ingredients
Directions
The book says “a moderate oven”. The 350°F (175°C) in the steps is the modern equivalent, not the book's own figure.
Prepare the potato topping
Boil the potatoes until tender, then mash them smoothly.
Mix in salt, melted butter, and the egg yolk.
Prepare the beef
Cut the beef into thin slices, removing fat and gristle, or mince it finely.
Season the beef with salt and pepper.
Assemble and bake
Butter a shallow pie dish and place the beef inside.
Moisten the beef with gravy or stock and Worcestershire sauce.
Cover with a layer of mashed potatoes, roughen the top with a fork.
Bake in a moderate oven at 350°F (175°C) for about 45 minutes until hot and browned.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Potatoes
- Form the bulk of the mashed topping, giving a soft, starchy layer that browns on top.
- Beef
- Provides the savory meat base of the hash, sliced or minced so it cooks through evenly.
- Egg yolk
- Enriches the mashed potato, adding richness and helping it hold together and brown.
- Butter
- Adds fat for richness and flavor in the potato topping and helps the top brown.
- Worcestershire sauce
- Adds savory, tangy depth that seasons the beef as it moistens.
The step that matters
Roughening the potato top. A fork-textured surface creates more exposed area, which browns more deeply in the oven. A smooth top stays pale and can dry or steam unevenly.
Swap the potato
How well each one fits the dish's main ingredients (beef, pepper, butter, egg, sauce):
- Capsicumfits better
- Asparagusfits about as well
- Potatothe original
- Tomatofits about as well
Fit is the average pairing score against beef, pepper, butter, egg, sauce. Candidates are from the same food group and used in at least 100 recipes.
