Wow! Thanks for all your advice and the website is great. Now here's an outrageous tenderizing trick: my Greek friend who grills octopus says that he tenderizes it by putting it in the washing machine or dryer with no heat/water just lets it bang around! I don't think I'll be doing it that way but it did make me laugh. I'm going to experiemnt this weekend and let you all know how it turns out.
