The pairs that carry this dish. Each one is judged two ways: how much their aromas overlap, and how often cooks already put them together.

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

What each ingredient does

Flour
Provides starch and structure so the mixture holds its shape when cooked.
Mashed potatoes
Supply the bulk and moisture that give the cakes a soft, tender interior.
Milk
Adds moisture and helps bind the flour and potato into a smooth dough.
Egg
Acts as a binder that helps the cakes hold together while frying.

The step that matters

Frying until golden brown on both sides. Medium heat lets the outside brown through the Maillard reaction while the centre heats through. Too high a heat browns the surface before the interior is cooked, and too low a heat leaves the cakes pale and greasy.

Swap the potato

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

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

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