I live on an island and octopus is eaten here, but not all that often. There are certain times of the year when we have an abundance of octopus in our lagoon and people will trap them to control the population. When this happens we cook it. However, cooking octopus is time-consuming if you want to make it taste like anything and not be tuff. It is a bit difficult to clean and prepare. Here is how I do it and it is delicious and it doesn't look like an octopus when it is done and served.
The octopus needs to be pounded with a rock or a piece of wood before it can ever be cooked. This will take time to do this one. when this stage is done, you'll need to boil the octopus with a green mango. You'll need to cut up the mango and cook it in the water with the octopus. This needs to be boiled for around 1 hour or so. Once this is done you can take this from the pan and make a curry sauce and cook it in this and add coconut milk to the curry sauce. This is delicious and it is like eating any other fish that comes out of our lagoon when it is cooked like this. It even looks like small pieces of cut up fish.
