I just received this fish today. I did not ordered this. Our supplier had it and I got.
Japanese Spanish mackerel is not good name. Americans don't like mackerel but some are really like.
Aji is Japanese mackerel and we call Japanese jackfish.
Sawara is same group as mackerel and snapper. Winter is better than spring. I ate a piece of nigiri sushi today and was delicious. It had good fat in meat. Please try it.
