Unfortunately I stuffed them first before freezing them and shudder to think my efforts might be in vein.
LOL!
I misunderstood your post at #201. I thought you meant whether you should cook the mushrooms before using them as stuffing for the turkey.
And, I may still be misunderstanding your post.
I gather you wanted to make stuffed baked mushrooms. I don't see why you would want to freeze them, unless you bought them ahead of the meal. Unfreeze them! Stuff them, and stick them in the oven. When is dinner time? I'm not far from Central Ave. :)
Good luck.
