D'var Halacha

We are continuing in siman 1, where the Chayei Adam is discussing preparing bran for animals. We learned that even if one adds water before Shabbos, it cannot be mixed on Shabbos in a normal fashion. One must employ a shinui. The Chayei Adam described two methods, either pouring between two containers, or a criss […]

  We are continuing in siman 1. We have seen the Chayei Adam bring the opinions mentioned in the introduction: the machlokes Rabbi Yosi Ben Rabbi Yehuda and Rebbi, and the machlokes between the Rambam and other rishonim regarding the difference between bar gibul and not bar gibul. The Chayei Adam concluded that we are

  We are beginning Klal 19, which discusses the melacha of losh. Losh is translated as kneading, because it is the closest English word which describes the losh process. However, it does not fully capture the melacha. The melacha is the process of combining a solid together with a liquid in order to create a

  We have finished Klal 18, and are discussing a few points not mentioned in the Chayei Adam. If a person makes tea and wishes to remove the teabag on Shabbos, if they remove the teabag and allow the water within the teabag to drip out, it is merakeid. The paper of the teabag is

  We are beginning siman 3, which discusses a scenario of unintentional merakeid. The Chayei Adam will give the example of one who wishes to transport a food item which has both small and large pieces. The smaller pieces are generally the unusable pieces, and the person wishes to transport the mixture in a sieve.

  We are continuing in siman 2, where we began learning about merakeid for the purpose of airing out the flour, without separating any impurities. We learned that it is assur miderabanan, because, although it is not an act of separating, it is using a kli unique for merakeid.    The Chayei Adam ends the

  We are beginning siman 1. The Chayei Adam writes that if a person performs an act of sifting, they are culpable for the issur deoraysa of merakeid. Parenthetically, the term merakeid comes from the word rikud, dance. When a person shakes a sifter, the particles inside look like they are dancing. If a person
