The main ingredient selected is domestically caught Spanish mackerel landed in Japan. By pan-frying, the fish remains intact even when stir-fried with vegetables, offering a fluffy texture.

For its development, users from Pal System Saitama cooperated. Users with elementary school-aged children and older collaborated on ingredient selection and usability considerations, motivated by the desire for "children to eat both fish and vegetables." The decision to use Spanish mackerel was based on its mild white flesh, making it easy for children to eat, and the fact that pan-frying makes bones less noticeable.
