The gas top ovenBefore you use the oven you should wipe it out with a damp cloth toremove any dust.You can only cook on one shelf at a time. You should turn food roundduring the cooking time.PreheatingYou do not need to preheat the top oven for casseroling and so on.Preheat the oven for baking or when you are cooking sensitive foodsuch as Yorkshire puddings, soufflés and yeast mixtures.When you are cooking or reheating frozen or chilled food read theinstructions on the packaging. When you are using the top oven to cookor reheat convenience food you should preheat the oven to gas mark 8.When you need to preheat the oven, we recommend you do so for20 minutes.Oven shelvesThe shelf in the top oven is different from the shelves in the main oven.You can distinguish the top oven shelf from the main oven shelvesbecause it has a metal plate attached to it. The shelves provided for themain oven should only be used in the main oven. Similarly, only use thetop oven shelf in the top oven.Shelf positions are counted from the top downwards.Most top oven cooking should be carriedout using the shelf provided in shelf position 2.However, when cooking a small joint or adeep cake you can use the top oven shelf onthe base of the top oven to allow enough air tocirculate around the food.RoastingFor best results we recommend open roasting, with or without a trivetusing minimal fat or oil to prevent splashing.It is not necessary to cover meat or poultry or wrap food in foil whenroasting as this restricts the circulation of heat and will lead to extendedcooktimes.If you are using a roasting bag or cover chicken breast with foil, beprepared to allow an extra 10 - 15 minutes for each 1/2kg (1lb).When cooking large items such as turkeys, the use of foil may berequired to prevent the breast becoming dry before the rest of the bird isfully cooked.Z C M 5 6 0 015The ovensShelf on base
