I brought this up on a Hirhurim comment thread, but was ignored. So let me bring it up here.<br><br>Motzi-Matza. The practice of eating two k'zeisim is cited in shulchan Aruch O"C 475, even though it is only quoted by the Rosh, (and then of course the Tur) and not the Rambam or Rif, who say that one k'zayis is enough. At first and second and third glance, this seems to be based on the perceived need to have one kzayis from the top matza and one kzayis from the middle matza. "Ein Osin Mizvos Chavilos Chavilos" seems to mean we don't bundle mitzvos together, but take each one separately. <br>
<br>What are the two mitzvos under discussion? What is the Mitzvah of "Motzi"? Eating lechem at a yom-Tov meal, I presume. This is considered a separate mitzvah from the one to eat a kzayis of matza on Leil Tes-Vov? The Biyur Halacha doesn't understand the need for two kzeisim and all but rejects the Shulchan Aruch (and Rosh's) approach, commenting that it is cited nowhere in Shas or the other main rishonim. <br>
<br>Since this practice is associated with the fact that the bracha is made over two matzos, is there any reason for a person who is not
eating from the matzos located on the seder plate to eat two k'zeisim?
After all, this person is not eating one k'zayis from the top matza and
one k'zayis from the middle matza anyway. He's eating from the box matzos that the host is passing around.<br><br>Raffy<br><br>PS As an aside, would the Shulchan's Oruch's preference for swallowing both kezeisim simultaneously disprove the Noda Beyehudah and Chazon Ish's shiurim right off the bat?!<br clear="all">
