Hi, your recipe described "Line 2 baking pan with heavy aluminum foil..." and i want to know in the event you bake 2 pans at a person time or 1 tray at any given time. My issue is the fact i wished to bake 2 tray at a person time so that I'm able to help save the electrical power Price and likewise produce a big quantity of bak kwa in one go.Everyt
