I don't have much experience cooking with dried and salted fish, but as far as I have read traditional recipes start with a long soaking time in water (and also changing the water multiple times) to get rid of the excess salt, followed by poaching or confiting in olive oil.

I have cooked fresh fish many times sous-vide with excellent results at around 50C. I suspect due to an extensive amount of salt, probably, changing the protein structure of the fish; this temperature might not work for rehydrated and desalted fish.

As per this question confiting is covered and another recipe for confiting sous vide also suggests 65C. However in these recipes, next to confiting, the main aim is to extract the gelatin from the fish to be later used in the sauce.

However I wasn't able to find much information on replicating poaching results with sous vide.

Does anyone have experience or resources regarding cooking temperatures for rehydrated and desalted fish.

  • Do you mean sous vide cooking after soaking, or instead of soaking?

  • I mean soaking and then sous-vide cooking, sorry if it wasn’t clear.

    I think you're right about wanting a higher temperature; in standard cooking, you boil the salt cod at a roiling boil, something you'd never do with fresh fish. However, I've never tried to sous vide it.

    One problem you'd have is that typically the cooking medium carries away some more of the salt, and of course in a plastic bag it wouldn't.

The purpose for salting fish is to cure it (originally for preservation). It does not need to be cooked. The reason for soaking and/or boiling salted fish is to remove the excess salt and to rehydrate the fish for consumption. Sous vide probably doesn't make sense in the preparation of salted fish, but I'd be curious how it comes out. You should soak to remove salt to taste. Be sure to taste the inner flesh when testing for saltiness.

For sous vide preparation, I would suggest soaking in cold water to remove enough salt and then cooking at a lower temperature. 50°C is a good temperature, but you can go even lower for salted fish. You might experiment as low as 40°.

    Salting cod is to dehydrate and increase the shelf life. It is generally not boiled to rehydrate, rather, it is soaked in cold water, which is changed multiple times. The rehydrated fish can then be used in a variety of applications, usually cooked, but not always.

  • @moscafj — There are different ways people prepare which includes soaking and/or boiling. See thespruceeats.com/de-salting-salt-fish-instructions-2138097. I have seen die-hard salt fish fanatics who advocate the boiling method. You could be right that most people soak and not boil, but I don't know the statistics.
