Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Hot mashed potato
- Forms the body of the croquette and gives a soft, tender interior.
- Butter
- Adds fat for richness and a smoother, more tender texture.
- Boiled lean ham
- Provides the savoury meaty flavour that defines the croquette.
- Cream
- Adds moisture so the mixture stays soft and easy to shape.
- Raw egg yolk
- Binds the mixture as it sets with gentle heat, helping it hold its shape.
The step that matters
Stirring in the egg yolk. The yolk must be beaten in and stirred constantly over heat so it thickens and sets the mixture without scrambling. Stirring spreads the heat evenly, so the mixture binds well enough to hold its cork shape when formed and fried.
