[Avodah] Raw food on Erev Shabbos

[I. Balbin]

I heard Rav Schachter mention (yutorah.org shiur on bishul b'shabbos) in the name of Rav Soloveitchik that there are two hanhogos for the following situation:

Erev Shabbos, just before licht tzinden, someone places a kettle containing tap water on a Grufa uKtuma heat source. According to those from Lita, it is mutar, presumably because the person is mesiach daas from the kettle. I assume the same holds for placing a raw chicken in one our regular ovens. (some put it in a metal box I believe so that there is no Mechze K'Mvashel) The minhag of Galicia (and I assume the rest of Poland) is to be choshesh to the Kasha by Rabbi A. Eiger on the Mechaber as brought in his comments to the Mishna in Shabbos "Ain Zolin" on 19B in reference to the Rashbo in Shabbos 36B where the Rashbo is also choshesh for "Shemo Yagis"

How are people Noheg (both for liquid (eg water) and solid (eg chicken, or perhaps cholent)?

Personally, we always make sure dry is machol ben drusoi or yad soledes ....
