My dad in New York introduced me to canned mackerel as an alternative to canned tuna. It's a bit more fishy in flavor, but not excessively, and has overall a better flavor than most average canned chunk light tuna. And it doesn't have the dolphin problem, and because it's a smaller fish, it doesn't have the mercury problem. Best of all, it's super-cheap.
In New York, your typical supermarket will have 6 oz. cans of boned, skinned mackerel, right next to the tuna. But here, I've only been able to find 15 oz. cans of mackerel with the bones and skin, which are a great value but more time-consuming to clean (and then you have to eat it a lot to use it up before it goes bad).
I've looked at Safeway, Cala and Tower so far. Does anybody have a suggestion as to where I could find small cans of mackerel? Thanks.
