The Cod should still have a chill on it from the refrigerator.
Room Temperature fish can become a health hazard
Pat the Cod dry using a paper towel (Important Step)
Cover Cod with Olive Oil, Honey Mustard (or favorite Mustard) & Sea Salt (Optional: Old Bay seasoning)
Place the Cod on an oven safe plate.
Place the Cod in the middle of the Oven
Roast the single portion for 5 to 6 minutes @ 450
Tip: If you're cooking more than one piece of Cod
One Additional piece: Add 2 minutes to the cooking time
Two Additional pieces: Add 4 minutes of the cooking time
Three Additional pieces: Add 5 minutes to the cooking time
There comes a point of diminishing return when increasing the cook time and all ovens cook differently. Think, less time is better until you get the hang of cooking the desired number of pieces of Cod in your oven. Just keep an eye on it. You can use your fingers to lightly press the Cod and see hows the cook is going in the oven. Should still feel somewhat soft when coming out of the oven.
