I graduated from White Croaker in Avila (didn't keep any) to some of these Pacific Mackerel in Morro Bay. I only kept one and wanted to try something with it. Decided to do Japanese style Mackerel Sujime. The fillet (leave pin bones in until after) is cured with salt for an hour or two then dropped in a Rice Vinegar, Mirin, Sugar, Salt bath for a few hours. Result is quite tasty. Today I was reading a bit more about Mackerel and it seems to be one of the healthier fish with reasonably low mercury accumulation.
