ר' אליעזר ממיץ

Rabbi Eliezer ben Samuel (known as Rabbi Eliezer of Metz) was a Rishon whose halachic rulings are cited in the codifiers. He appears in the discussion of the laws of Pesach, in the context of chametz that has become mixed with other food during the festival, a matter treated in Orach Chaim 447.

In the recorded passage, his view is brought alongside the leading authorities of his era regarding whether even a trace amount of chametz renders a mixture forbidden, and whether such a prohibition extends to deriving benefit or applies only to eating. His position is weighed together with those of other Rishonim in clarifying the practical halachah.
