Cooking cod is simple as long as you have a few tips up your sleeve.  The key to perfect cod lies in how long it is cooked – too little and the flesh may be tough and chewy, while overcooking can lead to dry and flavorless results.  A general rule of thumb when cooking cod is 3-4 minutes per side. Although this depends on the thickness of the cut you're working with – make sure it's at least an inch thick for best results.  The conventional oven method works well, too; aim for 15-20 minutes at 350 degrees. It's also important to check for doneness with a fork rather than relying solely on time – any extra minute or two could mean you lose out in terms of texture and taste!
