DY -“RM”A says the pots which very much sounds like that’s their Shabbos food (certainly their only hot food, which is considered a tzorech gadol).”
Exactly, it’s says pots. You have no idea whether this is Shabbos food or just any food. Also, it doesn’t say whether there was other hot food or not. Don’t put words into the S’A that it doesn’t say. If it doesn’t specify that it’s a case of Tzorech Godol, why are you assuming it is?
I’ll go out on a limb here -I think even hello99 would agree with me here!
