Cut hard-boiled eggs into quarters and sprinkle with salt.
Shape the balls

Fry in hot oil until golden brown and serve hot.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Potatoes
- Form the soft, starchy body that encases the egg and holds the shape.
- Hard-boiled eggs
- Provide the firm, filling centre of each ball.
- Butter
- Adds richness and softness to the mashed potato.
- Milk
- Loosens the mashed potato so it is smooth and easy to shape.
- Eggs
- Beaten eggs bind the flour and help the bread crumbs adhere to the outside.
- Bread crumbs
- Form a crisp, golden browned outer crust when fried.
The step that matters
Let the mashed potato cool before shaping. Warm potato is soft and sticky, so it tears around the egg and is hard to coat evenly. Cooling firms the starch so the balls hold their shape through breading and frying.
