Abstract
A package of food containing a substantial amount of water and solidified grease that can be cooked within the package in a microwave oven. A pad adjacent the food comprises microwave radiation transparent generally hydrophobic liquid grease absorbing materials that are capable of holding the amount of grease in the food when it is melted; and a vapor tight microwave radiation transparent enclosure surrounding the pad and food includes means for venting steam from the enclosure as the food is cooked. Preferably, the pad is produced from microfibers constructed of a composition comprising a blend containing substantially equal parts by weight of polypropylene and poly 4-methylpentene-1.
