Why it works: Beef and onion are a kitchen classic. They rank in the top 7% of all ingredient pairs, and cooks put them together in 17,092 recipes. Both carry 2-isopropyl-3-methoxypyrazine, which smells earthy, pea. The science ↓

Ingredients
Directions
Prepare the beef
Remove skin and gristle from the beef and mince it finely with the onion.
Season the mixture with pepper and salt, then dust with flour.
Cook and serve
Melt butter in a stewpan, add the minced mixture, and stir in beef gravy and ketchup or oyster sauce.
Cook for 10 minutes until fully dressed and serve.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Beef
- Provides the main body and savory meaty flavor of the dish.
- Suet
- Adds fat that keeps the minced meat moist and rich as it cooks.
- Flour
- Dusted over the mixture to lightly thicken the juices and help bind the sauce.
- Beef gravy
- Adds liquid and savory depth that forms the sauce around the meat.
- Onion
- Adds aromatic sweetness and moisture when minced with the beef.
The step that matters
Cooking the minced mixture. Stirring in the flour-dusted meat with liquid needs gentle, steady heat so the flour thickens smoothly instead of clumping, and the meat cooks through without drying out.
