Q. 2) (See question above, on serving hot fleishig cholent on the same plate people ate their shmalzherring). Most important, since the cholent it is a hot solid dovor gush, why is it not mevashel the oil of the herring, left on the plate?

A. Horav Shlomo Miller’s Shlit”a opinion is that considering a dovor gush or hot solid food item, that was transferred to one or more vessels, as still maintaining the original heath of the first keli, is only a chumrah, (Magen Avraham 318: 45, Mishna Berura 45). or stringency that you may be lenient on, in cases where it is an unintentional melocho or dovor sheino mischaven, since the user is not aware and does not care about cooking the oil left on the plate. It is also a doubtful act, since it may avoid the oil remnants altogether as mentioned in above question. Therefore, if one clears the plate with a napkin or places the hot cholent in another area of the plate, it would be permitted. Additionally, the cholent may qualify as a liquid, since even dry cholent, does spread something and adopts at least partially, the shape of the plate.
