The discussion revolves around the term "kadrai" featured in a YouTube video about puffing rice. It is clarified that "kadrai" likely refers to the cooking vessel, specifically an aluminum pan similar to a wok, rather than an ingredient. The video suggests a method for puffing rice without oil and sand, indicating that the white powder added to the rice may be salt. The term "kadrai" is identified as Lithuanian, meaning 'frame' or 'group', but in this context, it is primarily associated with the cooking apparatus used in the process.
