Containers to use
Choosing the correct container is a very important factor in deciding the success or failure of your cooking.
Testing Dishes for Suitability
When unsure that a cooking container is suitable for use in your microwave, check by the following test:
1. Fill a microwave safe measuring jug with 300ml (1⁄2pt) cold water.
2. Place it on the turntable alongside the dish to be tested. If the dish you are testing is a large dish, then stand the measuring jug on top of the empty dish.
3. Heat on HIGH power for
1 minute.
Result
If the dish is suitable for microwaving, it will remain cool, whilst the water in the jug will begin to feel warm. If the testing dish feels warm, do not use as it is obviously absorbing microwave energy.
N.B. This test does not apply to plastic or metal based containers e.g. Le Creuset® style dishes, which should not be used as they are cast iron covered with enamel.
QUICK CHECK GUIDE TO COOKING UTENSILS
OVEN GLASS
Everyday glass that is heat resistant e.g. Pyrex®, is ideal. Do not use delicate glass which may crack due to the heat from the food. Do not use lead crystal which may crack or arc.
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.
CHINA AND CERAMIC
Everyday glazed china plates, saucers, bowls, mugs and cups can be used if they are heat resistant. Porcelain and ceramic are also ideal. Fine bone china should only be used for reheating for short periods, otherwise the change in temperature may crack
the dish or craze the finish. Do not use dishes with a metal rim or pattern. Do not use jugs or mugs with glued handles, since the glue can melt in a microwave.
FOIL/METAL CONTAINERS
NEVER ATTEMPT TO COOK IN FOIL OR METAL containers – the microwaves cannot pass through and the food will not heat evenly – this may also damage your oven. Small items in shallow foil containers can be REHEATED in the microwave, but take care that
containers do not touch the oven walls or door. Use wooden kebab sticks instead of metal skewers. DO NOT
