Driven out of the kitchen by her stepmother, Lin Manru, Su Tang has no choice but to cook three simple home-style dishes over an old stove in the backyard: winter solstice tofu, Qingming soup, and Laba porridge. No one expects these three dishes to set the food world ablaze and spark a nationwide hunt for their flavors. When Zhou Yanzhi, a retired Michelin-starred chef, brings her a keepsake from his grandmother, when her adoptive brother Shen Zhiyao secretly steals her recipe book, and when her mother's ashes surface in an old woman's radish crock at the night market, she finally understands: every taste of home cooking is a code to her family's blood debts. She has no interest in power, yet with a single bowl of soup, she shakes the foundations of a trillion-yuan dining empire.
