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

What each ingredient does

Potatoes
Form the bulk of the casserole, giving it a starchy, tender body when baked.
Eggs
Bind the shredded potato mixture so it holds together when baked and set.
Condensed milk
Adds richness and sweetness and keeps the shredded potatoes moist.
Bacon
Adds fat and smoky, savory flavor, with drippings carried into the casserole.
Onion
Adds savory aroma and sweetness when cooked gently until yellow.

The step that matters

Soak shredded potatoes in condensed milk right after shredding. Raw shredded potato oxidizes and darkens quickly and loses starch-water, so soaking it immediately in milk protects its color and keeps the texture moist rather than dry or grey after baking.

Swap the onion

How well each one fits the dish's main ingredients (potato, condensed milk, egg):

  1. Chivefits better
  2. Capsicumfits about as well
  3. Asparagusfits about as well
  4. Onionthe original

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