If cod heads are highly salted, soak them overnight.
Rub off the discolored skin and wash them well.

Skim off any scum that rises to the surface.
Drain well and serve on a napkin with egg sauce and melted butter.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Cod sounds
- Forms the main body of the dish, becoming tender and flaky when gently boiled.
- Cold milk
- Mixed with water to make the poaching liquid, adding a mild, creamy richness to the fish.
- Egg sauce
- Adds richness and a smooth, creamy contrast to the mild boiled fish.
- Melted butter
- Adds fat and richness, carrying flavor over the cooked fish.
The step that matters
Skim off any scum that rises to the surface. Proteins and impurities released during boiling form scum that can cloud the liquid and taint the flavor. Removing it keeps the fish clean-tasting and the broth clear.
