I won't share the youtube link since this is too easy and you don't need to waste over 10 minutes on a video. I got 8 octopus over the weekend. I like them but they always come out tough. I always just pitched them in a pot and did a mild boil. This chef does basically the same thing with a simple twist. He gets a pot of salted water boiling, then dunks the octopus for about 20 seconds...removes from water and waits a couple minutes, then re dunks. He does this 3 times then puts the octo back in the water at a high simmer for 20 minutes...then cuts the heat and lets it set in the water for another 20 minutes. It just melts in your mouth and leaves the nice, mild flavor intact....I couldn't believe the difference just a little finesse could make.
