Rabbi Akiva Eiger defends his position that the R"Sh holds food does not emit even its own intrinsic taste, citing the R"Sh's own question about vegetables as proof. He explains that Tosfos' resolution regarding dissolving fat is directed specifically at reconciling the R"Sh's view, and offers a new analysis of why the Tur framed his question around milk cooked in a meat pot. He leaves unresolved whether originally-permitted meat taste absorbed in vessel walls can create a new Torah-level basar b'chalav prohibition.
