Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Sweet potatoes
- Form the bulk of the croquette, providing starch and moisture that give a soft, tender interior.
- Butter
- Adds fat for richness and a smoother, more tender texture in the mash.
- Eggs
- Bind the mashed potato so the croquettes hold their shape when fried.
- Bread crumbs
- Form a crisp outer crust that browns during frying.
The step that matters
Frying in hot fat until light brown. If the fat is not hot enough, the coating absorbs oil and turns greasy before it crisps. If it is too hot, the outside browns before the interior heats through. Steady heat gives a crisp, evenly cooked croquette.
Swap the sweet potato
How well each one fits the dish's main ingredients (butter, egg, pepper, bread):
- Capsicumfits better
- Asparagusfits better
- Chivefits better
- Sweet potatothe original
Fit is the average pairing score against butter, egg, pepper, bread. Candidates are from the same food group and used in at least 100 recipes.
