How to cook trout
Preheat the oven to 450 degrees fahrenheit (230 degrees celsius).
Meanwhile, cut four sheets of heavy-duty aluminum foil.
The pieces of aluminum foil should be cut into squares that are 3 inches (7.6 cm) longer than the length of your rainbow trout.
If you only have light aluminum foil, cut eight sheets. Double up the sheets to create four thicker squares.
