Traditional food is innovation that was successful already long ago. A sustainable food future requires development of many delicious with foods much less environmental impact than the current westernized foods. Intuitively it makes sense to build on tradition for this innovation leap. From the omnivore’s paradox (Rozin, 1976; Fischler, 1980, 1988) it is known a balance between novelty and familiarity is necessary for a food to be successful. Some of our previous research demonstrates that high familiarity is a prerequisite for accept of novel beers, and that an optimal level of novelty exists (Giacalone, Duerlund, Bøegh-Petersen, Bredie, & Frøst, 2014). Recent research investigating Indonesian millennials perception of a selection of traditional Indonesian foods demonstrates that traditional foods are more liked in their original version, compared to modernized versions (Fibri & Frøst, 2018). Modernized versions often lose their authenticity, and it is necessary to find ways to best preserve it. In addition it is vital to reinvigorate traditional raw materials and ingredients, such as the use of local soy bean varieties for tempe, a traditional Indonesian stable (Fibri, 2018). Sustainable traditional plant-based foods from one part of the world, such as Indonesian tempe, requires a gastronomic and innovative approach to be accepted in other parts of the world. We have developed novel ways of processing tempe and explored local nordic legumes as raw materials (Guixer, 2015; Guixer, Frøst, & Flore, 2017). Recent work from students (Corbet & Santos Bertran, 2018; Hartmann & Brønnum, 2016), indicates ways forward for successful introduction of tempe to the Danish market. References Corbet, L.
