In this chapter, the author introduces action case research as a methodological approach within Culinary Arts and Meal Science, suggesting that it can be used to generate context-specific research ideas and questions. By using an example study of natural cider making from surplus apples in central Sweden, specifically the Bergslagen region, the author demonstrates how this methodology can serve as a precursor to hypothesising and fostering “out-of-the-box” thinking within transdisciplinary approaches. The study reveals a latent gastronomic landscape within private homes and gardens, emphasising the potential of overlooked resources. Insights into a dynamic and continuous design approach for sustainable product development are also provided. In sharing this methodology, the author seeks to inspire colleagues to explore similar approaches, which could lead to new insights and advancements in the field of Culinary Arts and Meal Science, especially regarding sustainable food systems.
