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

What each ingredient does

Fish
Provides the savory protein that flakes through the hash and gives it its main flavor.
Potato
Adds starch for body and bulk, and its surface browns crisply in the hot pan.
Salt pork
Renders fat for frying the hash and adds savory, salty flavor.

The step that matters

Cook covered until brown, then fold like an omelet.. The lid traps steam so the mixture heats through, but browning needs direct contact with the hot pan. Let the underside set and brown before folding, or the hash will steam and stay pale and soft.

Swap the potato

How well each one fits the dish's main ingredients (fish, pork, pepper):

  1. Capsicumfits about as well
  2. Potatothe original
  3. Tomatofits less well
  4. Asparagusfits less well

Fit is the average pairing score against fish, pork, pepper. Candidates are from the same food group and used in at least 100 recipes.
