Selecting Quality Oyster Mushrooms

Visual Quality Indicators

• Fresh oyster mushrooms display vibrant, consistent coloring
• Caps should be firm and free from dark spots or slimy areas
• Gills underneath caps appear clean and well-defined
• Stems remain firm without signs of drying or shriveling

Texture and Aroma Assessment

• Quality specimens feel firm yet flexible when gently handled
