Wow! I never knew you could eat that either, PP! I kinda wish God had put an edible label on stuff so that when we're lost or in need we could eat stuff OK without poisoning ourselves.
Up here in northern Maine we eat fiddleheads. Not sure if you folks down there know about that yet or not. They are the unfurled young ferns that grow along streams and rivers and such. Here's a pic:
These are awesome with a little butter and salt. Do you guys do fiddleheads down there?
I haven't tried them yet, but it is on my to do list.
Oh man...those are GOOD. Important to pick them before they unfurl, but just before they do. Also, you need rinse the brown plant material off them so that they are pure green before boiling them.
