##There is a debate whether this is merely a rabbinic prohibition of uvdin d'chol, or a biblical one of tochen.<ref>See Teshuvat Harivash siman 184, who presents both of these options. Shulchan Aruch 321:10 states that one may not grind up cheese with a special cheese grinder, even though cheese doesn't grow in the ground and thus isn't subject to tochen. Clearly, then, this is prohibited rabbinically because of uvdin d'chol, as Mishna Brurah 321:36 explains. However, the Mishna Brurah 321:45 is concerned that when tochen would be relevant (like on vegetables), then cutting them with a designated utensil might constitute an isur deorayta. This is analogous to the melacha of borer (lit: sorting), in which it is permitted to do borer by hand, but prohibited biblically if the kli is designated for borer. The Biur Halacha (321:12 s.v. midi) elaborates on this idea as well.</ref> | |||
