Plastic
Many plastic containers are designed for microwave use. Only use Tupperware®containers if they
are designed for microwave use. Do not use Melamine – although it is heat resistant it absorbs
microwave energy and scorches. Even if a container is microwave safe, do not use for cooking
foods high in sugar or fat. Foods that require long cooking times e.g. brown rice, should not be
cooked in plastic. Never cook in margarine cartons or yoghurt pots, as these will melt with the heat
from the food. Many plastics that are not heatproof for cooking are suitable for defrosting.
Pottery, earthenware, stoneware
If completely glazed, these dishes are suitable. Do not use if
partially glazed or unglazed, since they are able to absorb water
which in turn absorbs microwave energy, making the container
very hot and slows down the cooking of food.
Foil/metal containers
NEVER ATTEMPT TO COOK IN FOIL OR METAL con tai ners –
the microwaves cannot pass through and the food will not heat
evenly – this may also damage your oven. Use wooden kebab
sticks instead of metal skewers.
