The importance of tolerating interstices: Babushka markets in Ukraine and Eastern Europe and their role in maintaining local food knowledge and diversity

Babushka informal markets selling several homemade gastronomic plant and animal-based products and culinary preparations, as well as wild and cultivated plants, and sometimes family butchered barnyard animals are extremely popular in Ukraine. In this field study that we conducted over a few years we inventoried the most relevant food plant products sold in these markets and we analysed how these markets represent remarkable food refugia for several local niche foods.In addition, we researched the historical and socio-economic reasons for the start, survival, and revival of this phenomenon, which had its origin during the Communist period. We furthermore evaluated similar recent trends in other Eastern European countries and especially those which had a very different post-Communist trajectory with the aim of addressing the possible factors affecting their survival and what could be done to preserve their existence. In particular, in a few of these countries (i.e. Azerbaijan) we observed how informal food markets represent experimental fields where gastronomic knowledge is not only "preserved", but also reinvented, possibly in response to the preferences and requests of a city's customers.
