DELICIA baking sheets are excellent for baking sweet and savoury meals alike. They are provided with a highly resistant non-stick coating that prevents overcooking. Instructions for use: thoroughly wash and dry the new sheet; smear the inside with a thin layer of cooking oil or butter and if needed powder with flour before every use. Avoid using utensils with metal ends; never cut or slice meals directly in the sheet! Do not overheat empty sheets! Leave to cool entirely before washing wash with normal detergents avoid scourers and sand-based agents; leave to soak if excessively dirty. Suitable for electric gas and hot-air ovens. Dishwasher safe although you should reduce or eliminate dishwashing in order to preserve perfect functioning and appearance.
