Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Potatoes
- Form the bulk of the croquettes, giving a soft, starchy body that holds the shape.
- Matzo meal
- Absorbs moisture from the mash and binds the mixture so the croquettes hold together.
- Onion
- Adds savory sweetness and aroma as it softens and browns in the pan.
- Mushrooms
- Contribute savory, umami depth and moisture to the filling.
The step that matters
Frying the croquettes. Frying over medium-high heat for a full 8 minutes per side browns the outside and sets the crust, helping the croquettes hold together and stay crisp rather than breaking apart or soaking up oil.
Swap the onion
How well each one fits the dish's main ingredients (potato, mushroom, pepper):
- Capsicumfits better

- Onionthe original
Fit is the average pairing score against potato, mushroom, pepper. Candidates are from the same food group and used in at least 100 recipes.
