Well, believe it or not, if you pick them early in the spring while they are in the "fiddle" stage and cook them as you would asparagus they taste quite similar. I wanted to pick some this year but I couldn't remember which ones are the edible ones. I was taught by an an old friend long ago beside the fact that its been at least fifteen years since I've eaten them. I believe it is the branched type that are known to carry cancer causing agents whereas the straight leaf type are edible at that stage. BUT, as I said its been so long now that I may have that backwards, which wouldn't surprise me because Sumac is another plant that there are two types... one is branched and the other is straight stick type of plant... the branched Sumac is edible while the straight Sumac is poisonous.
When I was a kid I tried smoking fern stems... very Sour
Yeh.... tried cornsilk too... along with other
Nothing beats a refreshing cup of corn squeez'ns out of a full silo though.
Honestly I just put it in there figuring there are probably some bacteria and yeast on the leaves of the fern though. Although I haven't even drained the MT yet so I doubt its doing any good.... or bad?
