Baking salmon at 0 degrees Celsius (which is basically the freezing point, not a cooking temperature) is not practical or safe for cooking. Salmon needs to be baked in an oven at typical cooking temperatures, generally ranging from about 350°F to 425°F (175°C to 220°C). For reference, a common baking temperature for salmon is around 375°F (190°C), baking for about 12-15 minutes until it is cooked through and flakes easily. Cooking times vary according to thickness and oven temperature, but 0°C is not a cooking temperature for baking salmon or any food. Thus, baking salmon at 0°C would result in it remaining frozen or raw for an indefinite time and is not a correct or recommended practice. The salmon must be baked at a suitable oven temperature (e.g., 350-425°F or 175-220°C) to cook properly.
