Pesach- Shirayim and Chametz Before Pesach - מכירת חמץ של שיריים שקבלו מצדיק

From Rulings and insights from the Lubavitcher Rebbe - Rabbi Chaim Wolosow by R Chaim Wolosow.

The Rebbe discusses how to handle shirayim containing chametz before Pesach. Despite possible halachic solutions like selling or hefker, the accepted minhag is to consume them beforehand, preserving their sanctity without retaining chametz. https://www.torahrecordings.com/shulchan_menachem/orach_chayim/226
