Ingredients

Directions

The book gives no oven temperature. The 350°F (175°C) in the steps was added when the recipe was transcribed, as a starting point.

Prepare

  1. Boil and mash the potatoes.

  2. Mix in the grated ham (or herbs/parsley), chopped onion, salt, pepper, nutmeg, and egg yolks.

  3. Form the mixture into balls.

Bake

  1. Cook the balls in a moderate oven at 350°F (175°C) until golden.

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 balls and give them a soft, starchy body.
Egg yolks
Bind the mashed potato so the balls hold their shape.
Grated ham
Adds savoury flavour and richness to the potato mixture.
Onion
Adds aromatic flavour to the potato mixture.

The step that matters

Forming the balls. The mashed potato must be cool enough and evenly mixed with the egg yolks so the balls hold their shape. Warm or loose mixture can spread or crack in the oven, and uneven mixing leaves weak spots.

Swap the onion

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

  1. Spinachfits better
  2. Capsicumfits better
  3. Asparagusfits better
  4. Onionthe original
