Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Mashed potatoes
- Form the bulk of the croquette and give a soft, tender interior.
- Butter
- Adds fat for richness and a softer, more tender texture.
- Milk
- Adds moisture so the mashed potato mixture can be shaped smoothly.
- Beaten egg
- Binds the mixture together and helps the crumbs adhere to the outside.
- Cracker crumbs
- Form a crisp, golden coating that browns during frying.
The step that matters
Fry in hot oil until golden brown. If the oil is not hot enough, the croquettes absorb excess oil and turn greasy, while the coating may not crisp before the interior heats through. Frying at a steady hot temperature browns the crumbs quickly and keeps the inside moist.
Swap the potato
How well each one fits the dish's main ingredients (butter, milk, nutmeg, pepper, egg):
- Capsicumfits about as well
- Potatothe original
- Spinachfits about as well
- Asparagusfits less well
Fit is the average pairing score against butter, milk, nutmeg, pepper, egg. Candidates are from the same food group and used in at least 100 recipes.
