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

What each ingredient does

Raw irish potatoes
Provide the starch and bulk that form the bulk of the pancake.
Eggs
Bind the grated potato together and help the cakes hold their shape.
Onion
Adds aroma and savory flavor to the potato mixture.
Coconut oil or butter
Conducts heat in the skillet and promotes browning on the cake surfaces.

The step that matters

Cook until golden brown on both sides. Grated potato releases water and starch, so cakes can steam or stick if the pan is not hot enough. Medium-high heat with enough fat lets the surface brown and crisp before the centre is cooked through.

Swap the coconut

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

  1. Avocadofits better
  2. Pumpkinfits about as well
  3. Coconutthe original
  4. Limefits about as well

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