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 ↓
To Make Colops of Cold Beef
Ingredients
Directions
Prepare
Remove all fat from the cold beef and cut it into thin bits.
Chop the onion finely.
Boil enough water or gravy for the sauce.
Make the sauce and serve

Stir and shake until the sauce thickens and the meat is cooked.
Remove the sweet herbs and serve in a dish.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Cold beef
- Provides the meat that is cooked through in the sauce.
- Butter and flour
- Rolled together, they thicken the sauce as they melt and mix into the liquid.
The step that matters
Adding the butter rolled in flour to boiling liquid. Flour needs heat and constant stirring to thicken without lumps. Adding it to boiling liquid and stirring and shaking helps it disperse evenly and gelatinize into a smooth sauce.
