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

What each ingredient does

Salt fish
Forms the main body of the dish and supplies its savoury, salty flavour.
Potatoes
Add bulk and a soft, starchy body that holds the fish together.
Butter
Adds richness and fat, and helps the top brown in the oven.
Warm milk
Adds moisture and softens the mixture so it spreads and bakes evenly.
Flour
Sprinkled on top, it helps form a golden, browned crust during baking.

The step that matters

Bake until a rich brown. Browning comes from heat acting on the surface sugars and proteins, so the dish needs enough time in the oven. Pulling it too early leaves the top pale and soft, while baking too long can dry the mixture out.

Swap the potato

How well each one fits the dish's main ingredients (fish, butter, milk, flour, egg):

  4. Chivefits about as well

Fit is the average pairing score against fish, butter, milk, flour, egg. Candidates are from the same food group and used in at least 100 recipes.
