DY -“(although I still disagree).”
I would never be Choshet you to ever agree with me. 🙂
“Where did the M”B qualify that it’s a mitzvah gemurah only if you have no other main course? He just says “tavshil cham”.”
You see this is what happens when you mix up Simanim in the S’A just for you to ask Kashas.
There are obviously two types of Tzorech Godols.
One type of Tzorech Godol would be Matir Ameira L’acum by a D’oraysa like we see in 276.
Another type of Tzorech Godol would be Matir Ameira L’acum by Shvus D’shvus L’chatchilla like we see in 325.
So you’re correct in 325 it doesn’t have to be “no other main course”. Or it could be that even though he just says “Tavshil Cham”, it has to be similiar to Mashkeh where obviously you don’t have any other for Kiddush.
