I harvested 38g of blue oyster mushrooms just a few days ago! It took about 55 days to get to 100% colonization, then another 15 days to fruit, a total of 70 days. I waited for the caps to flatten out but because the top side grew heavy, the base stem snapped off before it had the chance to do so.
A few days later, I sauteed it with some garlic, butter, parsley, and seasoned it with salt and pepper. It was juicy, flavorful and tasted a bit like ham.
