set cooking time is up.
If you use two baking trays at the same time,
keep one empty level between them.
Cooking meat and fish
Leave the meat for approximately 15 minutes
before carving so that the juice does not seep
out.
To prevent too much smoke in the oven
during roasting, add some water into the
deep pan. To prevent the smoke
condensation, add water each time after it
dries up.
Cooking times
Cooking times depend on the type of food, its
consistency, and volume.
Initially, monitor the performance when you
cook. Find the best settings (heat setting,
cooking time, etc.) for your cookware, recipes
and quantities when you use this appliance.
