Mackerel is one of my favorite fish to eat. And miso is the perfect flavoring agent for it. Why is miso is the perfect flavoring agent for mackerel? As you may know, mackerel can have a strong flavor. The miso is equally, if not more strong in flavor, and does a good job showing the mackerel who’s boss. But it definitely needs the help of a side kick, known as ginger. Make this Japanese style mackerel with miso part of your next Japanese meal and all you need is a bowl of rice!
