Pressure cooker \Pressure cooker\
   1. (Cookery) a pot with a lid which may be tightly bound to
      the bottom part, forming a vessel which can withstand some
      gas pressure from within. It is used to heat foods in
      water or steam to a temperature somewhat above the boiling
      point of water, allowing the cooking process to be
      accomplished more quickly than otherwise.
