Fry and drain
Fry in deep fat until golden brown and drain on brown paper.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Riced potatoes
- Form the soft bulk of the croquette and absorb the cream and cheese for a smooth interior.
- Grated mild cheese
- Adds richness and flavor and helps bind the mixture as it melts.
- Heavy cream
- Adds moisture and fat, keeping the potato mixture tender rather than dry.
- Egg
- Yolk enriches and binds the filling; beaten white creates a coating that helps breadcrumbs stick.
The step that matters
Coating with breadcrumbs and egg white. The beaten egg white must fully cover each shape before the second breadcrumb roll, otherwise the crumbs can fall off or leave bare spots that open during frying and let the soft filling escape.
