Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Potatoes
- Provide the starchy bulk that holds the mixture together and gives a soft interior.
- Codfish
- Supplies the main flavor and savory body of the balls.
- Butter
- Adds fat for richness and a tender, moist texture.
- Eggs
- Bind the mixture and, when whipped, help make the balls light.
The step that matters
Drying the mashed mixture on the stove. Any leftover water makes the mixture loose, so the balls can break apart or spatter when dropped into hot lard. Drying the potatoes and fish well lets the starch and protein set firmly once fried.
Swap the potato
