The presentation is very important. I covered a plastic serving tray in aluminum foil and lined it with lettuce leaves. To get the tentacle onto the plate I arranged overlapping lettuce on top (soon to be the bottom) of it and then held the plate over it and inverted everything. It sounds tricky but worked out easily. The foil mold should lift off easily and the plastic wrap will peel off cleanly provided there aren't any nasty wrinkles. My tentacle was a few inches too long so I cut the excess into pieces and arranged them on the plate. The piece on the very end was discarded (read: eaten). As a finishing touch I spooned corn syrup mixed with some remaining juice over everything to give it an extra gloss.
If I was doing it again I would have set out some nice serving utensils and made a gross syrupy sauce with tapioca balls floating in it served in a gravy train. I found some really interesting exotic fruits at the Asian market that would have looked good on the plate, but they were out of my price range.
Though quite simple I think this method has potential to make some pretty interesting creations and I'd love to see what you can come up with. If you try this the only thing I ask of you is to post pictures.
one more time thx 4 the idea and greetings from mexico
