HE ATE CHAILEV THE SIZE OF AN OLIVE AND A HALF. WAS THIS ONE PIECE (OF WHICH HE REMEMBERED HE ATE AN OLIVE-SIZED PORTION) OR WAS THERE TWO PIECES NAMELY AN OLIVE-SIZED PIECE AND ANOTHER SEPARATE HALF PIECE?
Chazan Michael Plaskow, Netanya, Israel
What is important is that the K'zayis and the half k'Zayis were eaten in one Ha'alamah (without realizing in between that he had sinned). It makes no difference whether they were one piece or two pieces, or even whether he ate them within the time limit of a K'dei Achilas P'ras or not. The fact is that half a Shi'ur is not Chashuv and does not therefore require a Yedi'ah. This enables it to combine with the k'Zayis when he remembered having eaten it, and this in turn, prevented it from combining with the second half-k'Zayis and obligating him to bring a second Korban.
