פירוש על עבודה זרה 137:3

We can see here how the concept of “imparts taste” is transformed into a concept of set ratios. The early amoraim operate through a system of imparting taste. This is a sensible system but hard to follow—who wants to taste the mouse beer or vinegar. Therefore, to solve the problem, they come up with set ratios. The latest voice in the Talmud gives the same ratio to everything—60 to 1. In Hebrew this is called “batel beshishim” and is a very important concept in halakhah.
