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 savory meat flavor and the chewy, shredded bulk of the hash.
Potatoes
Supply starch that gives the hash its body and crisp-browned edges.
Onions
Caramelize while cooking, adding sweetness and depth of flavor.
Butter
Adds fat for richness and helps the onions and potatoes brown.
Water
Moistens the mixture so the potatoes cook through and the hash stays tender.

The step that matters

Cook the onions until browned and tender. Onions need enough time over medium heat for their sugars to caramelize, which builds sweetness and color. Rushing this leaves them sharp and pale, so the hash tastes flat.

Swap the onion

How well each one fits the dish's main ingredients (beef, potato, butter, pepper):
