Zei The ovens manufactured by COVEN work through hot air circulation Such system allows you to cook pastas roasts to grill to bake pastries to thaw frozen foods During cooking thanks to COVEN ovens foods lose less weight and volume and there is a 50 saving on seasonings Hot air must be allowed to circulate both over and under the food that s being cooked Leave free air tracks with a thickness of at least 4 cm Since the edges of pans are an obstacle to the circulation of air do not use pans or baking tins with edges higher than necessary Leave a little space between the products placed on the same baking rack between a chicken and the other one etc To grill put meat directly on the oven s rack To cook food with pans or baking tins use directly the oven s racks inserting them into the side slides To cook pastries and pizzas the use of baking sheets is recommended To prevent the surface of baked pastas from getting too dry cover it up with a kitchen foil riddled with holes to allow the evaporation of cooking fumes In order to achieve excellent results it is essential to preheat the oven until it reaches the cooking temperature 18 COVEN COOKING ADVICE ROASTS GAME POULTRY The bigger the pieces to cook the more moderate the temperature should be about 180 C with higher temperatures roasts might be more cooked outside than inside Chickens are better and faster coo
