Lots of people prefer to bake their fish by wrapping it in foil. This method is very efficient, as it cuts down on oven and utensil cleaning time.
By wrapping the fish in a protective covering, it has a similar effect to steaming, as moisture is sealed within the foil rather than escaping into the oven. This is an excellent way to ensure that your fish does not dry out and it also helps to seal in aroma and flavour.

Preheat the oven to around 400°F (200°C) and grease the base of a large piece of foil with butter. Take the piece of fish and season it with salt and pepper. Place the fish onto the foil, add some herbs and lemon juice, fold up the sides of the foil and seal at the top. Place into the preheated oven and cook for the specified time until the flesh is white and firm.
