As well as the traditional pressure cooker, there are now plastic pressure cookers for the microwave. Tupperware, Nordic Ware and Meyer all make microwave models.
These light weight models heat up easily and cool down quickly. “Saturated steam, combined with microwaves, quickly cooks, while retaining more flavor and tenderizing meats.”
