How to make
After washing the defrosted mussels with hot water, place them on the bottom of a fire proof tray. Chop the basil finely, mix it with the butter and then spread this mixture on the clams.
Grate cheese on top, cover it with a lid or aluminum foil and bake in the oven at 360°F (180 °C) for about 20 minutes. Finally, leave for a while with the lid open until the cheese turns pink.
