Directions
Prepare the potato mixture
Mash the cold potatoes in a pan.
Add melted butter, salt, pepper, cream, and the beaten yolk of one egg.
Rub the mixture together for about five minutes until smooth.
Shape and coat

Dip each ball into a beaten egg, then coat with bread crumbs.
Fry
Fry in boiling lard until golden brown.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Mealy potatoes
- Their starch makes the mixture soft and absorbent, forming the body of the croquette.
- Butter
- Adds fat and richness, giving the filling a smooth, tender texture.
- Cream
- Adds moisture and softness to the mashed potato mixture.
- Egg
- Binds the filling and, as a coating, helps bread crumbs stick and set.
- Bread crumbs
- Form a crisp outer crust that browns during frying.
The step that matters
Rub the mixture until smooth. Working the mashed potato with fat and liquid until smooth gives an even, cohesive texture; lumps or uneven mixing can make shaped balls crumble or fry unevenly.
