A couple falls ago a fellow worker gave me what he called a "sheepshead". It was about the size of a basketball. He gave me some suggestions for cooking and told me it would keep in the 'fridge for a week. First recipe I tried was frying in olive oil and garlic. Excellent. Second recipe was breading after dipping in egg and water w/ "frying magic" and again frying in olive oil. Excellent. Had to give some to my mother along w/ my successfull IMO recipes. Long story short, the mushroom the size of a basketball was consumed in a week, never had to worry about how to preserve.

An aside: the following spring, my interest piqued for mushrooms, I found some morels at the end of my driveway, of all places. I spent the next several evenings after work hiking and searching for more in the agricultural area I live. Never found one.
