In Shulchan Aruch Yoreh Deah Siman 89 Sif 3 we find the following rule. According to the Machaber if one ate a "tavshil shel baser", then, in order to eat cheese afterwards, one must only wash their hands (no waiting time is required). However, the Rema argues and says that eating a tavshil shel baser is like eating regular baser (meat) and one must wait before eating cheese (whatever amount of time you would normally eat after eating baser before eating cheese).
My question is: What is a "tavshil shel baser"? What would be a "classic" example? Are there any sources or poskim that gave actual examples of what a tavshil shel baser is?
(I have always thought (as an example) for it to be the potatoes, beans, or eggs cooked in a cholent that has meat in it. However someone suggested to me that that case would have a stricter rule than discussed in the Shulchan Aruch here, since perhaps these foods have on or inside of them "residue" or "shuman" (fats) from the meat and would be then considered to be like the baser itself. However, this doesn't seem to be the case from the language of the Rema that further explains that if there was no meat in the pot that this "tavshil" was cooked in then would be muter to eat cheese afterwards without waiting (see the mafarshim that have difficult with this since seemingly this din is pashut because of nat bar nat).)
