The food history of Irkutsk is deeply intertwined with Siberian culinary traditions, where the harsh climate and the unique cultural mix have given rise to a distinct cuisine. Indigenous Buryat influences, along with Russian culinary traditions, shaped the local food scene. Being located near Lake Baikal, the deepest and oldest freshwater lake in the world, Irkutsk boasts an abundance of freshwater fish, which has historically been a staple of the local diet. Root vegetables, wild herbs, berries, and grains have also been integral due to their storage capabilities during the long winters. With the Trans-Siberian Railway's arrival in the late 19th century, Irkutsk became a melting pot of flavors with increased accessibility to various ingredients and influences from travelers.
