Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs

What each ingredient does

Fillet of beef: Is the main cut that is cooked and eaten, so its size sets the roasting time.
Vinegar: Acidic marinade that softens the surface of the meat and adds tang.
Onion: Adds aromatic flavour to the marinade as it steeps into the beef.
Fresh parsley: Adds fresh herbal aroma to the marinade.

The step that matters

Soaking the fillet for two days. Long soaking in an acidic marinade changes the outer layer of the meat and carries seasoning inward. Draining well before wrapping matters because surface moisture stops the beef from browning evenly over the fire.
