Much has been written in the last several years about the addictive qualities of dairy products due to a certain protein found in great abundance in cowâs milk: casein. Perhaps it was Dr. T. Colin Campbellâs seminal work, The China Study, that was the catalyst for this new understanding of dairy addiction.
Cooking time will vary greatly depending not only on the cut of fish but also the cooking method. In general, your cod will be done when it reaches an internal temperature of 54Â°C (130Â°F), regardless of cooking method.
Fish has always had one temperature for being done. The internal temperature for a done fish should be 145 degrees. At this temperature the fish should be opaque throughout and flake easily when tested with a fork. Like you, I prefer my Salmon to be medium, so the internal temperature will not be 145. As far as the internal temperature for other fish. I think you will need to test some fish to find the right internal temperature for the way you like your fish cooked. I know that on Cod and Halibut, I under cook mine a little so it is moister. But I never have checked the temperature, but will next time.
