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 croquette.
- Eggs
- Bind the mixture and set when heated, holding the croquette together.
- Butter
- Adds richness and fat for a tender interior and flavor.
- Cracker crumbs
- Form a crisp, browned outer crust when fried.
The step that matters
Chilling the coated croquettes. Cooling firms the starchy, egg-bound mixture so it holds its shape. Skipping the chill can let the croquettes break apart or absorb oil during frying.
Swap the sweet potato
How well each one fits the dish's main ingredients (butter, egg, cream):
- Leekfits better
- Potatofits better
- Asparagusfits better
- Sweet potatothe original
Fit is the average pairing score against butter, egg, cream. Candidates are from the same food group and used in at least 100 recipes.
