A Poor Man's Matzah

A poor man baked matzah from a sack of flour and afterward found a little dough stuck inside the sack. The Saba Kadisha judged the amount so small that, even had it fallen into the flour, there was enough flour to nullify it. Still he hesitated to permit the matzah, because some authorities are strict even about dough that is not stirred back in. Yet he did not want to forbid it either. The man was poor, could not easily buy new flour, and would lose the joy of the festival. So the Rav searched for a basis to permit. His responsum shows the balance of a true posek: he did not bend the halacha, but he also would not let it be applied as if the person in front of him were not there.
