before useGB-9using aluminium foil in your microwaveIt is safe to use aluminium foil in your microwave oven as long asyou follow these safety guidelines.As with all metal, microwave energy cannot pass through foil, butprovided that you keep the foil away from the side of the oven itwill not cause sparks and there will not be any damage toyour oven.Using foil is a good way of shielding parts of food that you do notwant to cook as quickly as others – perhaps where the food isnarrower and would otherwise overcook.Place the foil over the area you want to shield, taking care thatthe foil will not touch the sides of the oven when the turntable ro-tates. Only use one piece of foil at a time so that you do not getsparks between the separate pieces.Follow these guidelines when using foil in your microwave:● Remove foil lids from containers before using in the microwave. Some lids are made of card with a foil covering – theseshould be removed too. Use a microwave-safe transparent lid ifpossible.● Stir food during cooking if the container has a lid or film cover.● Always use the glass turntable.● Use shallow containers with a large surface area. Do not usecontainers that are more than 1.25in (3.5cm) deep.● Use oven gloves when handling hot foil containers.● Do not completely cover food with foil. The microwave energycannot pass through the foil so the food will not cook.● Do not let aluminium foil touch the inside of the oven.● Do not use more than one piece of foil in the oven at the sametime.
