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, giving a soft, starchy interior once mashed.
- Butter
- Adds fat and richness, keeping the mashed potato smooth and moist.
- Egg
- Binds the mashed potato and, brushed on, helps the crumbs adhere.
- White bread crumbs
- Form a crisp outer coating that browns when fried.
The step that matters
Fry in hot fat until golden brown. If the fat is not hot enough, the coating absorbs oil and turns greasy before it crisps, and the potato inside may not heat through. Frying in properly hot fat seals the crumb layer quickly and browns it evenly.
Swap the potato
How well each one fits the dish's main ingredients (butter, pepper, bread, egg):
- Capsicumfits better
- Asparagusfits better
- Chivefits about as well
- Potatothe original
Fit is the average pairing score against butter, pepper, bread, egg. Candidates are from the same food group and used in at least 100 recipes.
