The best season to consume mackerel is in spring.
Cooking the mackerel in a pressure cooker makes its bones tender enough to eat (the Japanese consider that the bones, rich in calcium, are very good for health).
Nitsuke means stew in Japanese. It is typical and authentic Japanese home cooking. Use Umeboshi (salted plum) if you can find it at the organic grocery store. The sourness of the plums makes this fish stew delicious.
