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 dish; their starch crisps into a browned crust when pressed in hot fat.
Lard
Conducts heat and fries the potatoes, giving them a crisp, browned surface.
Onions
Browning in the pan adds savory sweetness and aroma to the potatoes.
Butter
Adds richness and flavor, and helps the crust brown further.

The step that matters

Press the mixture down and let it brown. Pressing the potatoes into the hot fat and leaving them undisturbed lets a crust form through browning. Stirring too early breaks that contact, so the potatoes steam rather than crisp.

Swap the parsley

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

  1. Garlicfits better
  2. Thymefits about as well
  3. Parsleythe original
  4. Capersfits less well

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