What each ingredient does
- Salt fish
- Cured, salty protein whose excess salt is drawn out by soaking before cooking.
- Melted butter
- Adds richness and flavor and coats the fish with fat for a smooth finish.
The step that matters
Soaking the salt fish. Soaking draws salt out of the cured fish through diffusion. Too short a soak leaves the fish overly salty, while changing the water keeps the salt gradient steep so the salt keeps leaving the flesh.
