I’ve no idea what the woman is talking about. I can only guess she’s talking about traditional bread making. I can recognise some words because I know them. Such as duona, ir, taip, pirma, druska, gaspadynia (Belarusian loan)
PS The plant (Sweet Flag, Latin : Acorus Calamus) woman puts in tray is growing on swamps. In traditional Belarusian bread-making the same plant is also used.
