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

What each ingredient does

Cold beefsteak
Forms the main body of the hash, providing protein and savoury flavour.
Butter
Adds fat and richness, helping the hash brown and taste rich.
Flour
Thickens the cooking liquid so the hash holds together rather than running off the toast.

The step that matters

Stirring in the flour. Flour needs to be cooked and mixed evenly into the hot liquid, otherwise it can clump and leave floury pockets. Stirring while it heats lets the starch swell smoothly and thicken the hash evenly.
