In this episode, chef Rika makes crunchy fried horse mackerel (a type of fish), marinated in a delicious sweet-and-sour nanban sauce. Vinegar has come to be known for its health and beauty effects, making this a great way to add more to your diet. For the side dish, she makes an easy simmered dish, allowing the flavors of soy sauce and dashi to soak into atsu-age fried tofu and spinach. Chef Rika also teaches how to make a deliciously gingery salad by cutting carrots, bell peppers and cucumbers into strips, then adding a dressing made with ginger (known to help improve blood circulation), sesame oil, and ponzu.
