Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Mashed potatoes
- Form the soft, bulky body of the croquette inside its coating.
- Egg
- Binds the mixture so the rolls hold their shape, and the dipping egg helps crumbs stick.
- Butter
- Adds richness and a tender, moist texture to the potato mixture.
- Cracker crumbs
- Form a crisp outer crust that browns when fried.
- Milk or cream
- Adds moisture and softness to the mashed potato mixture.
The step that matters
Shaping the rolls smooth. Smooth rolls with no cracks seal better when coated, so the crumbs stay on and less filling leaks into the hot lard during frying.
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.
