Why it works: Onion and potato 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 ↓

Ingredients
Directions
Prepare
Mince the meat, potato, and onion together.
Season the mixture with pepper and coarse sea salt.
Stir in enough hot stock, gravy, beef dripping, or water to moisten the mixture.
Cook
Heat enough beef dripping in a frying pan to cover the bottom.
Add the hash to the hot pan and stir for a few minutes.
Let it fry until browned on the lower side.
Finish
Turn it out into a hot dish and serve, or transfer to a greased baking pan.
Smooth the top and bake until browned on top.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Cooked meat
- Provides the main body and savoury flavour of the hash.
- Cooked potatoes
- Bind with the meat and add bulk and a soft, starchy texture.
- Onion
- Adds sweetness and aroma when browned in the mixture.
- Hot stock, gravy, or water
- Moistens the mixture so it holds together and browns without drying out.
The step that matters
Frying until browned on the lower side. The hash needs enough contact with hot fat to form a crisp, browned crust. Heat that is too low steams the mixture instead, leaving it soggy and pale.
