In this paper are presented the objectives and methods of the research of plant food remains from seven sites in Bulgaria and Northern Greece. The research is conducted in the broader context of the PlantCult Research Project. The project seeks to explore the “culinary cultures” of Prehistoric Europe and to reconstruct the culinary practices involving plant ingredients through an interdisciplinary approach. The main analytical tools are the macroscopic and microscopic examination of the archaeological finds and experimental replication, informed by ethnographic investigation.
