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

What each ingredient does

Mashed potatoes
Form a flat base that crisps and browns in the hot fat while staying soft inside.
Eggs
Provide a rich, runny yolk and protein that sets when fried, topping the potatoes.
Oil or butter
Conducts heat evenly and helps the potatoes brown and crisp on the surface.

The step that matters

Fry the potatoes until golden brown before flipping. Flipping too early tears the flattened potatoes apart. Letting one side form a firm, browned crust first gives structure and a crisp, flavourful surface, as the Maillard browning reaction develops on dry, hot surfaces.

Swap the potato

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

  1. Asparagusfits better
  2. Chivefits better
  3. Leekfits about as well
  4. Potatothe original

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