  • OU Kitniyot Kosher for Passover Supervision

    Previously the OU has not issued Hashgacha for retail Kitniyos products for Pesach, despite requests to do so. This was avoided over the concern that different Pesach symbols might confuse consumers. The OU has this year, on a limited basis, authorized the attached certification to appear on Kitniyos products: OU Kitniyot With an explanatory message: "Acceptable for those who consume kitniyot on Passover." The symbol is presented in such manner so as to avoid any confusion and the packages will not indicate Kosher for Passover except as indicated. This decision was taken at the urging of our Poskim, to benefit many Kitniyos consumers who relied on various assumptions (rather than actual Hashgacha) for Kitniyos Pesach products.

  • The Tempering of Grains and its Chometz and Hafrashas Challah Implications

    Rabbi Yitzchok Gutterman

    The milling of grains has been going on for millennia, and in all that time, the process has not changed dramatically. Milling is still done by simply grinding kernels, albeit with rollers instead of stones. Sifting is still done with sifters, although by automated machines instead of by hand. There is another part of milling known as tempering. Tempering refers to spraying grain kernels with water before they are milled. This makes the bran tougher and less brittle. If the wheat kernel has not been tempered, the bran may shatter and leave brown flecks (“ash”) in the flour when the kernel is milled. This is undesirable in regular white flour. Tempering strengthens the bran so that it is removed from the endosperm easily and does not cause brown flecks in the flour.

  • Kli Rishon & Kli Sheini

    Rabbi Eli Gersten

    Both a kli sheini and a kli rishon shelo al ha'aish are pots of hot water that will gradually cool down. Since it is difficult to distinguish between them, we require Tosafos's help to properly understand the distinction. Although they look almost identical, a kli sheini has difanos mikareros (walls that cool down the product) while a kli rishon shelo al ha'aish has difanos michamemos (walls that maintain the heat of the product). An extended irui is none of the above, for the simple reason that the walls of this pot will not cool down. So long as the irui continues, there is a heat source that is preventing the kli from cooling. For this reason it is most similar to a kli rishon al ha'aish.

  • Lo Basi Ella L’orer - Glass

    Rabbi Eli Gersten

    The laws regarding kashering glass are especially confusing, because the opinions range from one extreme to the other מקצה לקצה. • Rashba (Teshuva 1:233), Ran (Pesachim 9a) - glass is smooth, hard and does not absorb (or absorbs very little) and therefore does not need to be kashered. דשיעי וקשים ובליעתם מעוטה מכל הכלים • Ra’ah (Brought by Ritva Pesachim 30b) – Glass is boleya and is polet like metal, but may not be kashered with hagalah because we are concerned that it might crack, משום דחייס שמא פקעה. • Mordechai – Glass has the status of cheres, הואיל ותחלת ברייתו מן החול.
