HINTS ON MICROWAVE COOKING AND CLEANING
Arrange food in the microwave towards the outside edges leaving the centre empty. This allows the microwaves to cook the food from the centre as well as the outside.
Use less energy by covering foods in cling film or put them in microwave safe containers to hold in the moisture and speed up the cooking process.
Allow some standing time once the microwave has finished the cycle, especially if you are cooking roasts or baked products.
