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

What each ingredient does

Cold boiled potatoes
Form the bulk of the dish and brown lightly in the fat, giving a crisp-edged texture.
Beef drippings
Carry the heat and fry the onion and potatoes, adding rich savory flavor.
Minced onion
Adds aroma and savory sweetness as it cooks gently in the fat.

The step that matters

Frying the potatoes until delicately yellow. Cold boiled potatoes are already cooked, so the goal is only surface browning. Keeping the heat moderate and stirring occasionally lets the outside turn golden without scorching or drying the interior.

Swap the onion

How well each one fits the dish's main ingredients (potato, pepper, beef, parsley, lemon):

  1. Carrotfits better
  2. Spinachfits better
  3. Chivefits better
  4. Onionthe original
