Mushrooms
Mushrooms are culinary "sponges" that require specific handling to achieve their best flavor and texture. Because they are roughly 80–90% water, the primary goal of preparation is to manage moisture.
Remove mushrooms from plastic wrapping immediately. Store them unwashed in an open paper bag in the refrigerator; the paper absorbs excess moisture and prevents them from becoming slimy. MUSHROOMS
