The Sour Girl team is composed of a group of ordinary people: Onion Mom, Shiitake Sister, Water Caltrop Man, Beef Brisket Boy, Eggplant Sauce, Fermented Bean Curd A-Chi, Ginkgo TCM Doctor, and Baby Corn Big Sister. Breaking through the limitations of time and space, we dedicated ourselves to the creation of seasonal recipe content in the summer of 2017. In the spring of 2019, the team received the paid support of nearly 2,000 readers to independently publish Taiwan's very first cookbook that aligns with the four seasons. We believe that by living in harmony with the four seasons, easily sourcing seasonal ingredients, and stepping into the kitchen to cook—from understanding the ingredients to reconstructing the food preparation process—we grasp the very beginning of food safety, and we also gradually reclaim our own dietary autonomy. We hope to accompany our readers through their year-after-year cooking lives, helping them learn to face all the dietary choices before them, make better and better judgments, and ultimately, enable every reader to become a complete individual with "dietary self-awareness."
