Cholent pot was taken off the stove by accident and put into a second kli. The owner of the pot then realized the situation and was upset about this and wanted the pot put back on the stove…can one put the cholent (while still hot) back in the original pot and back onto the blech or is it a chazara issue?
Under these circumstances, where the food was actually taken out of the pot, the “siluk” (removal of the pot from the fire) is a complete siluk, and therefore the fact that the owner did not know about it will not help (based on Magen Avraham and Perishah; but see comment below, that under extenuating circumstances there is room to be lenient).
The fact that the owner did not know about the pot coming off the fire only makes a difference where the siluk is not complete.
See Rabbi Akiva Eiger 254, cited by the Biur Halachah (254:2).
Best wishes as always.
