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, Frizzled
Ingredients
Directions
Prepare the fat
Cook pieces of beef fat slowly until enough liquid fat is obtained; strain and return to the frying pan.
Fry the meat and potatoes
Heat the fat, add the cold meat, and fry quickly until lightly browned on both sides; remove and keep warm.
Add the onion to the pan and fry until nicely browned.
Add the cold potatoes, season with salt and pepper, and press down in the pan.
Fry until well browned, then turn and fry the other side.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Cold meat
- Forms the main body of the dish and browns to a savoury crust in the hot fat.
- Beef fat
- Provides the frying medium, carrying heat evenly and adding rich beefy flavour.
- Cold potatoes
- Crisp and brown in the fat, giving the dish its frizzled texture.
- Onion
- Browns in the fat, adding sweetness and aroma to the dish.
The step that matters
Pressing and turning the potatoes. Pressing the potatoes into the pan gives them contact with the hot fat so they brown and crisp. Turning only after a deep brown crust forms prevents them from breaking apart and steaming instead of frying.
Swap the onion
How well each one fits the dish's main ingredients (meat, beef, potato, pepper):

Fit is the average pairing score against meat, beef, potato, pepper. Candidates are from the same food group and used in at least 100 recipes.
