Bull Whip Kelp Pickles

I was cavorting in a kayak yesterday in the Monterey Bay and happened to drift into raft of kindly otters, one of whom was generous enough to offer me a 7 foot length of bullwhip kelp. I thanked him profusely, complimented him on his finely kempt coat and promised I would put the estimable sea vegetable to the best possible use. I have eaten exquisite pickled kelp before, but I admit, I have never made it. I have serious doubts that it could be fermented, so I made a sweet vinegar pickle, much like the one I tasted years ago. Soaked a bit then sliced in rounds and spears. They are rather fetching. I will let you know how they fare after a week or two, but I suspect a little salty, a little sweet, a little sour, a little spicy and a whole lot of fishy sea krauty crunch. Can there possibly be a superior confluence of flavors to tickle the taste buds?
