Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Cold mashed potatoes
- Form the bulk of the croquette and give it a soft, tender interior.
- Egg whites
- Beaten into the potatoes to bind the mixture and help the balls hold their shape.
- Egg yolks
- Form a coating that helps the crumbs or flour stick and promotes even browning.
- Flour or cracker crumbs
- Form a dry outer crust that crisps and browns when fried.
- Butter
- Adds richness and flavor to the potato mixture and to the frying fat.
The step that matters
Fry in hot butter or lard until golden brown. Fat that is not hot enough lets the coating soak up oil and turn greasy before it crisps. Hot fat sets the crumb crust quickly, so the interior heats through while the outside browns.
Swap the potato
How well each one fits the dish's main ingredients (pepper, butter, egg, flour):
- Chivefits better
- Shallotfits better
- Asparagusfits better
- Potatothe original
Fit is the average pairing score against pepper, butter, egg, flour. Candidates are from the same food group and used in at least 100 recipes.
