Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Potatoes
- Form the soft, starchy body of the croquettes and hold their shape when mashed smooth.
- Butter
- Adds richness and moisture, softening the mashed potato and carrying flavor.
The step that matters
Fry in smoking hot fat. Hot fat sets the crumb coating quickly so it browns and crisps before the filling absorbs grease. Fat that is not hot enough lets the croquettes soak up oil and turn greasy.
Swap the onion
How well each one fits the dish's main ingredients (butter, potato, egg, pepper):
- Chivefits better
- Asparagusfits better
- Capsicumfits better
- Onionthe original
Fit is the average pairing score against butter, potato, egg, pepper. Candidates are from the same food group and used in at least 100 recipes.
