Ingredients
Directions
Prepare
Soak the codfish in a pan of water overnight.
The next morning, separate and chop the fish.

Form and fry
Combine the mustard with the milk, then add it and the fish to the mashed potatoes. Mix everything thoroughly and form into round balls.
Fry the balls in hot Cottolene and serve immediately.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- White codfish
- Provides the main body and flavor of the balls once soaked and flaked.
- Potatoes
- Starch that mashes into a binder, holding the fish together in the formed balls.
- Cottolene
- Fat that adds richness to the mash and conducts heat for frying the balls.
- Milk
- Adds moisture that keeps the mashed potato mixture soft and easy to shape.
The step that matters
Fry the balls in hot Cottolene. The fat must be hot enough to brown the outside quickly. If it is too cool, the balls absorb oil and turn greasy before they set and heat through.
Swap the mustard
How well each one fits the dish's main ingredients (potato, milk, pepper):
- Capsicumfits better
- Carrotfits better
- Tomatofits better
- Mustardthe original
Fit is the average pairing score against potato, milk, pepper. Candidates are from the same food group and used in at least 100 recipes.
