Any pie dough, cookie dough, cake, brownie, cornbread, bread dough, will work fine. Only fill the removable pan one half or less. You must back with the lid closed. You can then add any filling you like. One of my favorites is to make birds nests from potatoes like hashbrowns and then fill with scrambled eggs the way you like. Your imagination is your limitation I have a book that can be emailed if you request it
Just saw your response to an old question - I just got a Black and Decker Shell Maker at a white elephant sell for $.75 - figured for that price I could wing it - HA HA - if your offer of emailing instructions is still on the table I would very much appreciate it. THANKS
