I'm braising 2 octopus for tonight's tapas dinner. I got fresh octopus as opposed to frozen. I couldn't remember whether or not to lop off the heads and so I didn't. After braising for a minute or 2 one of the heads exploded and out came this green goop. I quickly took the other one out and cut off the head. It's continuing to cook, goop and all but I can't remember, is this goop good or bad? Please don't tell me that I have to throw out the whole dish!
