The facts
About blue oyster
Timeline
First harvest about 7 to 14 days after you cut. Pins often show in a week. Keep spraying for a second round in about 2 to 3 weeks.
As food
This is a cooking mushroom, lean and savory. Cook it all the way through and do not eat it raw.
Worth knowing
The blue gray color fades as the caps grow. That is normal. Pale rims usually mean you waited a day. Still good to cook.
Food and tea. Not medicine. The FDA has not reviewed this.
