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

What each ingredient does

Corned beef
Provides the main meat and savory salted flavor that defines the hash.
Potatoes
Supply starch that thickens the mixture and gives the hash its body.
Onions
Add sweetness and aroma as they soften and brown during cooking.
Egg yolks
Add richness and help bind the hash as they set with the heat.

The step that matters

Just before removing from heat, stir in the nutmeg and egg yolks.. Egg yolks set when heated, so adding them near the end binds the hash lightly without scrambling into curds. Cooking them too long makes the texture dry and grainy.

Swap the nutmeg
