The Chunhe Food Workshop in Lanzhou encounters a stove-stopping crisis. Chef Gu Shi'an amazingly resolves the predicament with limited ingredients, accidentally meeting Princess Ning'an who goes by the alias Xiao Man. Through twenty children's meal menus and rigorous tests of the four seasons, the two directly face commercial rivals' harassment, identity rumors, and ingredient traceability dilemmas. Gu Shi'an adheres to the original intention of food, avoids chasing luxury, values real diners' needs, and studies dietary standards. After breaking into the Palace Dietary Institute, he eliminates book-value waste, improves procurement and preparation systems, and writes the burning power of ordinary food with the folk wisdom of mortal life.
