The gas top oven
Before you use the oven you should wipe it out with a damp cloth to remove any dust.
You can only cook on one shelf at a time. You should turn food round during the cooking time.
Preheating
You do not need to preheat the top oven for casseroling and so on. Preheat the oven for baking or when you are cooking sensitive food
such as Yorkshire puddings, soufflés and yeast mixtures.
When you are cooking or reheating frozen or chilled food read the instructions on the packaging. When you are using the top oven to cook or reheat convenience food you should preheat the oven to gas mark 8.
When you need to preheat the oven, we recommend you do so for
20 minutes.
Oven shelves
The 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 shelves because it has a metal plate attached to it. The shelves provided for the main oven should only be used in the main oven. Similarly, only use the top oven shelf in the top oven.
Shelf positions are counted from the top downwards. Most top oven cooking should be carried
out using the shelf provided in shelf position 2. However, when cooking a small joint or a
deep cake you can use the top oven shelf on the base of the top oven to allow enough air to
circulate around the food.
Roasting
For best results we recommend open roasting, with or without a trivet using minimal fat or oil to prevent splashing.
It is not necessary to cover meat or poultry or wrap food in foil when roasting as this restricts the circulation of heat and will lead to extended cooktimes.
If you are using a roasting bag or cover chicken breast with foil, be prepared to allow an extra 10 - 15 minutes for each 1/2kg (1lb).
When cooking large items such as turkeys, the use of foil may be required to prevent the breast becoming dry before the rest of the bird is fully cooked.
