Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Mashed potatoes
- Form the main body of the croquettes, giving a soft, moist interior.
- Egg
- Binds the potato mixture so the rolls hold their shape, and the dipping egg helps crumbs adhere.
- Butter
- Adds fat for richer flavor and a softer, more tender interior.
- Cracker crumbs
- Form a crisp outer crust that browns during frying.
The step that matters
Shape the mixture into smooth rolls. Mixture that is too wet or loosely packed can crack or fall apart, and gaps let oil soak in. Smooth, firm rolls hold together and fry to an even golden crust.
Swap the potato
How well each one fits the dish's main ingredients (pepper, butter, milk, egg):
- Capsicumfits about as well
- Potatothe original
- Asparagusfits about as well
- Chivefits less well
Fit is the average pairing score against pepper, butter, milk, egg. Candidates are from the same food group and used in at least 100 recipes.
