remarks
Aluminium foil
Shielding only. Small smooth pieces can be used to cover thin parts of meat
or poultry to prevent overcooking. Arcing can occur if the foil is too close to
oven walls. The foil should be at least 1 inch (2.5cm) away from oven walls.
Browning dish
Follow the manufacturer’s instructions. The bottom of a browning dish must be
at least 3/16 inch (5mm) above the turntable. Incorrect usage may cause the
turntable to break.

Microwave-safe only. Follow the manufacturer’s instructions. Do not use
cracked or chipped dishes.

not heat-resistant and may break.

to allow steam to escape.

cooking.

short-term cooking only.
