An e-mail discussion on snacking before mussaf
---- ---- claimed that kiddush is unnecessary before snacking Shabbat morning between shahrit and mussaf. This is not the accepted halakha in most communities except in cases of duress. There have been poskim who maintained that the obligation for day kiddush is only after mussaf, and prior to that the halakha is similar to pre-shahrit. There also have been poskim who permitted "tasting" before daytime kiddush even when the time for kiddush arrived. However, Shulhan Arukh does not posek like either of these views.
Shulhan Arukh's formulation in OH 289:1 makes clear that once the time for kiddush arrived, kiddush is necessary before "tasting". When Shulhan Arukh in OH 286:3 states that a snack is permitted after shahrit before mussaf it is coming to exclude the opinion that prohibits having a snack before mussaf; this is not a kiddush halakha at all (see Bet Yosef). This is the unambiguous interpretation of Shulhan Arukh and p'sak of most of the leading poskim including: Birke Yosef, Mishna Berura, Arukh Hashulhan and Kaf HaHayim. (All on OH 286.)
Further On Kiddush Before Musaf
---- ---- mentioned several poskim through the centuries who held that "a little something" between shahrit & musaf is OK without kiddush as it is not yet time for kiddush. He informs us that Rabbi Obadiah Yosef in Yabia Omer (v. 5 OH 22:2) discusses the topic & cites two additional poskim of this opinion. However, he omitted to say that Rabbi Yosef cites many poskim that kiddush "is" required before snacking after shahrit before musaf, that it is the interpretation of Shulhan Arukh according to the most widely accepted authorities and that it is also Rabbi Obadiah Yosef's own p'sak.
