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 mashes into a soft, shapeable base for the croquettes.
- Butter
- Adds fat and richness, giving the mashed potato a smoother, softer texture.
- Eggs
- Yolks enrich and bind the potato mixture; the beaten egg helps bread crumbs adhere to the outside.
- Bread crumbs
- Form a crisp outer coating that browns when the croquettes are fried.
- Lard
- Serves as the hot frying fat that browns the coating and cooks the croquettes through.
The step that matters
Ensure the bread crumbs stay on when dipping in egg. Egg acts as glue for the crumb coating. If the coating is loose or thin, it can fall off in the hot fat, leaving bare potato that burns or breaks apart while frying.
Swap the potato
How well each one fits the dish's main ingredients (butter, egg, bread):
- Asparagusfits better
- Leekfits better
- Chivefits about as well
- Potatothe original
Fit is the average pairing score against butter, egg, bread. Candidates are from the same food group and used in at least 100 recipes.
