openmike - Sweet Chestnuts - before you put them under a grill or at the edge of an open fire, prick the shell with a sharp knife tolet the steam escape. Cook them until the outer shell (Not the green prickly bit - you have already removed the "Nut" ) goes black and charred. The inner "Brain - shaped" chestnut should be perfect for eating. When done under a grill, they often explode like popcorn, and that is a good hint thet they are probably done (if you can find the bits).
Quack!!!
