To extend shelf life, refrigerate fresh mushrooms in a paper bag; do not wrap in plastic or store in airtight container, as this will speed spoilage.
To freeze: (1) Wash mushrooms thoroughly and slice; (2) Steam mushrooms for three minutes or saute in butter or margarine until almost done; (3) Let cool, then package in airtight containers or freezer bags and freeze immediately.
Freezer time shown is for best quality only — foods kept constantly frozen at 0° F will keep safe indefinitely.
