Wondering how to really tenderize my cooked octopus I got from the fish martket. My goal is to make a braised version of Galician style octopus. (Octopus, olive oil, potatoes and paprika) This version is in bite-size chunks served as tapas, both times I've had it, it's been served in Spanish latas or cazuelas. I've tried to make it twice and although the flavor is where I want it, the octopus is rubbery! Both times I braised the octopus, potatoes and olive oil together in the oven for at least an hour and although the potatoes were perfect, the octopus was chewy. I really want melt in your mouth texture like I had at the restaurants. I am considering: 1. boiling octopus again (I bought it cooked) then braising 2. Braising longer, like 2+ hours? In oven or maybe on the stove with more liquid and adding potatoes the last 45 min. Any suggestions would be greatly appreciated!
