Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Potatoes
- Provide the starchy bulk that gives the croquettes their soft, fluffy interior.
- Butter
- Adds fat and richness, softening the potato mixture and improving its flavour.
- Egg yolks
- Bind the mixture and add richness so the croquettes hold their shape.
- Beaten eggs
- Create a coating that helps the bread crumbs stick and promotes even browning.
- Bread crumbs
- Form a crisp, golden outer crust when fried.
The step that matters
Keep the mixture firm before shaping. Potatoes that are wet or too soft will not hold their shape when formed and fried. Letting the boiled potatoes dry and keeping the mixture firm reduces moisture, so the croquettes keep their form and fry crisp rather than breaking apart or absorbing excess oil.
Swap the potato
How well each one fits the dish's main ingredients (butter, egg, nutmeg, bread):
- Shallotfits better
- Leekfits better
- Chivefits about as well
- Potatothe original
Fit is the average pairing score against butter, egg, nutmeg, bread. Candidates are from the same food group and used in at least 100 recipes.
