Frequently Asked Questions
Should you wash mushrooms or wipe them clean?
Contrary to popular belief, you can quickly rinse mushrooms - they don't absorb much water. Pat dry immediately. For a cleaner flavor, dry-brush them instead. Never soak mushrooms.
How do I get vitamin D from mushrooms?
Place mushrooms gill-side up in sunlight for 15-60 minutes. UV exposure converts ergosterol to vitamin D2. Some store-bought mushrooms are now UV-treated for enhanced vitamin D content.
