Fish is one of the healthiest foods for humans. It contains high quality protein, iodine, and various vitamins and minerals. But, unfortunately, many people rarely eat it, attributing this to the complexity of preparation and cutting. We offer you a simple and tasty recipe for cod fillet. Cod can be replaced with any white fish, such as hake, and pollock, navaga or pike perch. Sour cream gives the fish a delicate creamy taste and makes it juicy. The dish turns out to be very light, so you can safely eat it even for dinner.
