Ingredients

Directions

Prepare the batter

  1. Peel and grate the raw potatoes, then place the pulp on a sieve to drain the liquid.

  2. Add the egg, flour, salt, sugar, and grated lemon peel to the potato pulp to form a thick batter.

Fry and serve

  1. Heat butter in a pan and fry the mixture in small cakes, browning lightly on both sides.

  2. Serve very hot.

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

What each ingredient does

Raw potatoes
Provide the starchy base of the cakes, giving body and a tender interior when cooked.
Egg
Binds the grated potato and flour together so the batter holds its shape.
Flour
Thickens the batter and helps the cakes hold together during frying.
Butter
Fat for frying that promotes even browning and a rich flavour on the surface.

The step that matters

Draining the grated potato. Excess liquid from grated potato dilutes the batter and makes the cakes soggy and slow to brown. Draining on a sieve keeps the batter thick enough to hold its shape in the pan.

Swap the potato

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

  1. Arrowrootfits better
  2. Shallotfits better
  3. Leekfits better
  4. Potatothe original

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