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 croquette and, once mashed, give a soft interior that holds its shape.
- Butter
- Adds fat and richness, softening the mashed potato for a smoother texture.
- Cream
- Adds moisture and richness, keeping the mashed potato soft and easy to shape.
- Egg yolks
- Add richness and help bind the mixture so the croquettes hold together.
- Egg
- Forms a sticky coating that helps the crumbs adhere to each croquette.
- Bread and cracker crumbs
- Create a crisp, golden-browning outer crust when fried.
The step that matters
Fry in boiling lard until golden brown. The fat must be hot enough to crisp the crumb coating quickly. If it is too cool, the croquettes absorb grease and turn soggy before the crust sets.
