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

What each ingredient does

Cold roast beef: Provides the meat that becomes the savoury filling once simmered.
All-purpose flour: Thickens the stock or water into a coating that clings to the toast.
Soup stock or water: Supplies the liquid that cooks the chopped beef and forms the sauce.

The step that matters

Simmer covered over gentle heat. Simmering the flour-thickened liquid gently lets the starch swell and the sauce thicken evenly, while covering limits evaporation so the meat stays moist.
