Bacalao is easy to prepare but a bit time consuming. Bacalao is salted cod and to prepare it, you have to soak in water to remove the excess salt. Here's how to prepare bacalao (salted cod) for cooking.
The best method for soaking bacalao is to cover the fish with approximately 2 inches of cold water in a large bowl. Put the bowl in the refrigerator and soak for up to 3 days, changing the water at least 3 times a day.
Different brands and varieties of salt fish differ in degrees of saltiness. Less salty varieties need less soaking time, sometimes just one day. You can test it by tasting a small piece for saltiness after 24 hours of soaking. You want the bacalao to be slightly salty, not overpowering.
