Yeah it is the same as squid...you even catch them the same way as squid.
Very good eating...same as squid. I have not looked at the above links (but thanks for posting, I will take a look later). Cooking is the same as squid - either very fast or long and slow. Go anywhere between and it will be worse than your boot soles !!
I prefer hot and fast. A blazing red hot wok (make sure all your prep is done first cos this is quick !!). If your wok does not smoke oil instantly, it is not hot enough !!!...If it burst into flames it is PERFECT !!
Stir fry...like toss constantly really fast, like you see in the movies. 20 to 30 seconds...go over 30 seconds and you will be looking at at least 1 hour boil to get the "tender" back.
