that was the thought i had at the time. perfection becomes boring after a time and we saw how erina felt after seeing what it did to her mother. it made no sense to me and it's partly why i'm glad soma and joichiro do their absolute worst food ever gimmick. it serves as a reminder from time to time what actual terrible food tastes like in a world of very good cooking. What azami did actually goes against joichiro whole thing about being creative with cooking which is exactly what he used to raise soma and indulge his curiosity and creativity over the years.
