Kaseiinist

Kaseiinist refers to a traditional Finnish folk custom associated with the celebration of Christmas Eve, known in Finnish as *Jouluaatto*. The term itself is not widely documented in historical records, but it likely stems from the broader Finnish Christmas traditions that emphasize community, storytelling, and the sharing of food. During this time, families and neighbors would gather to enjoy a festive meal, often featuring dishes like *riisipuuro* (rice porridge) or *karjalanpiirakka* (Karelian pies), while reciting folk tales, poems, or singing carols.

The custom of kaseiinist may have roots in older pagan or pre-Christian practices, where gatherings around the winter solstice were common. Over time, these traditions merged with Christian observances, particularly the Eve of Christmas, which holds significant importance in Finnish culture. The word itself could be a regional or dialectal variation, possibly linked to the idea of "gathering" or "celebrating" in a communal setting.

While not as widely recognized as other Finnish Christmas customs like *joulupukki* (Santa Claus) or *joulukinkku* (Christmas ham), kaseiinist reflects the importance of togetherness during the holiday season. Today, it may be remembered more as part of the broader Finnish Christmas spirit, emphasizing warmth, hospitality, and the preservation of cultural heritage. The exact origins and regional variations of the term remain unclear, but it serves as a reminder of Finland’s rich oral and communal traditions.
