Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Sweet potatoes
- Provide the bulk and soft, moist body of the croquettes.
- Eggs
- Bind the mixture and set when cooked, holding the croquettes together.
- Butter
- Adds richness and fat, softening the texture and aiding browning.
- Hot milk
- Adds moisture and smoothness, keeping the mashed potato soft and pliable.
- Bread crumbs
- Form a crisp, browned outer crust when fried.
The step that matters
Fry the croquettes in hot fat until a rich brown. The fat must be hot enough to brown the crumb coating quickly. If it is too cool, the croquettes absorb excess oil and turn greasy before the crust sets and the interior heats through.
Swap the sweet potato
How well each one fits the dish's main ingredients (milk, butter, egg, bread):
- Potatofits better
- Asparagusfits better
- Leekfits about as well
- Sweet potatothe original
Fit is the average pairing score against milk, butter, egg, bread. Candidates are from the same food group and used in at least 100 recipes.
