For migrants, food is considered a functional element in preserving cultural identity and adapting to the social and cultural environment of the destination region. It can also be said that communities committed to their traditions can effectively preserve their cultural values ​​and habits in the regions they migrate to (Mutlubaş, 2025; 788-789). This study focuses on the wedding bread of Bulgarian immigrants (macır) living in the village of Geyikdere in Yalova province. The aim of this research is to document the oral culture and memory surrounding the intergenerational transmission of bridal bread, its purpose, preparation method, and timing, as well as the collective work tradition surrounding it, and to visually record the tradition of bridal bread. The research design, conducted using qualitative methods, is cultural analysis (ethnography). Data were collected using a semi-structured interview technique in line with the purpose of the research. The data obtained revealed that bridal bread is a type of bread that has been passed down from pre-migration settlements to post-migration settlements. Additionally, detailed information on the traditional bread recipe, preparation techniques, baking times, and the collaborative tradition surrounding bread were also recorded. The research data is important for documenting intangible folk culture in written and visual form.
