Abstract
Abstract A method of microwave cooking, heating and re-heating includes the steps of placing food to be cooked, heated or re-heated into a microwave compatible container having an open mouth thereof and, thereafter, applying over said mouth of said microwave compatible container an FDA grade waxpaper having a basis weight in a range of about 15/25 to about 30/40. Thereafter, the container is placed in a microwave oven for less than a prescribed period of heating for such food type and quantity. Alternatively, such FDA grade waxpaper may be tightly wrapped or enclosed about food to be heated and thereafter placed within a microwave oven, thereby dispensing with the use of any microwave compatible container.
