I like pumpkin seeds, both to nibble, and to chuck a handful into the bread dough.
I know you need particular varieties of pumpkin to be able to gather the edible seeds (they've gotta be 'naked' ones ;) apparantly), but apart from the eminently suitably named 'Lady Godiva' in the Organic Catalogue, I can't find any others. Is it a case of Hobson's Choice? Or does anyone have any other possibilities?
