The theme for this episode is marinating. Chef Saito and Yu Hayami marinate pork in miso, one of the most iconic Japanese cuisine ingredients, then saute it. Chef Saito shares the secret ingredient he adds to his miso marinade, in order to bring out the depth in its flavor. They also marinate green beans in a richly flavorful soup made with sesame seeds, vinegar, and dashi, for a light and tasty side dish.
