Our Spanish octopus is one of the best available because it holds onto most of its weight once cooked and gets a good alternative rating from seafoodwatch.org. The octopus comes in frozen, which actually helps tenderize the meat. To prepare the octopus, usually it is recommended to boil or put it in the slow cooker for a few hours to fully tenderize and cook it. From there, it can be prepared for a salad, the grill, etc. These 4-6 lb octopus typically cook down to around 1.5 - 2.5 lb of meat, which is suitable for 4-8 people.
