The pairs that carry this dish. Each one is judged two ways: how much their aromas overlap, and how often cooks already put them together.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Codfish
- Provides the main savory flavor and the flaky body of the balls.
- Potatoes
- Supply starch and bulk, binding the mixture so the balls hold their shape.
- Egg
- Binds the mixture together and helps the balls set when cooked.
- Butter
- Adds fat for richness and helps the surface brown when fried.
- Cream
- Adds moisture and softness, keeping the mash tender rather than dry.
The step that matters
Rolling and frying the balls. The mixture must be firm enough to roll, yet moist enough to stay tender. Frying at a steady heat browns the outside and sets the egg before the interior dries out.
Swap the potato
How well each one fits the dish's main ingredients (butter, cream, egg):
- Leekfits about as well
