R. Ashi offers the final resolution to the problem, which goes back to the first resolution. The pan in which sacrifices was cooked only needs scalding and not being made white hot. Although when it emits taste, that taste is also forbidden, like yayin nesekh, the taste is just taste. It is not visible. Since the taste is not visible, and when it absorbed the taste the taste was permitted, what it emits is less prohibited. Note that it still requires kashering, just a lesser form.
