This research observed the daily culinary practice of Taiwanese migrants in Thailand, it aimed to understand the cross-culture dietary habits and changes after migration by interviewing 18 female adults from these families。 Dietary habits, food ingredients, ways of cooking, person who cooks and cooking tools are the 5 main variables in this research. Research results indicate, firstly, Taiwanese migrants in Thailand use different channels to continue their home-cooking with Taiwanese flavors, because that’s what these families are familiar and accustomed to. Secondly, some dishes on these Thai-Taiwanese migrant’s dining tables are intermixed of Taiwanese and Thai flavors, the original Taiwanese ‘home-cooked’ flavor has been slightly changed. Finally, the reproduction of ‘home-cooked flavor’ in foreign country, not only represents nostalgia of Taiwanese society, but it also signifies the inheritance of hometown taste and one’s cultural identity.
