Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Codfish
- Provides the main flavor and the flaked body of the cakes.
- Fresh butter
- Adds richness and flavor, and helps the cakes brown when fried.
- Egg yolks
- Bind the mixture and add richness so the cakes hold together.
- Mashed potatoes
- Add bulk and softness, helping the cakes hold their shape.
The step that matters
Remove from heat when scalding hot.. Overheating the egg yolks can scramble them, leaving a grainy texture instead of a smooth, binding mixture.
Swap the potato
How well each one fits the dish's main ingredients (butter, egg):
- Asparagusfits better
- Chivefits better
- Leekfits about as well
- Potatothe original
Fit is the average pairing score against butter, egg. Candidates are from the same food group and used in at least 100 recipes.
