The first time I tried this was great!! I had, in my stash of "kitchen stuff", some Coquille Shells, so when I wanted an impressive appetizer for a special dinner...I just soaked the large shells in water for awhile. Instead of just putting the filled mushrooms in a pan to bake, and then transfer to plate, I transferred the beautiful filled shells. The soaked shells didn't break and it was truly spectacular to serve!! A different kind of 'Rockefella'!! PS. I also used "I can't believe it's not Butter", because at 65, I want us to be able to say "I can't believe we lived this Long", especially since I just have always loved to cook hearty!! LOL
