D'var Halacha

    We are beginning siman 23. The Chayei Adam writes that if Shimon is in one house, and Reuvein is in another house, and Shimon hears Reuvein make kiddush, if Reuvein has in mind to be motzi Shimon, Reuvein is yotzei even though they will be eating separate meals. The Mishnah Berurah adds that […]

    We are continuing in siman 4, which discusses kli sheini.    The Chayei Adam writes that, in his opinion, even though kli sheini does perform bishul, if it is hot enough that it is yad nichveis bo, it will have the ability to cook. The Chayei Adam is clearly not referring to kalei

We are beginning siman 4, where the Chayei Adam discusses kli sheini. The Chayei Adam writes that kli sheini does not have the ability to cook. As we have learned, kli rishon is defined as a container directly over the fire, or the hot contents of the container even after they have been removed from

  We are continuing in siman 3, discussing the concept of irui kli rishon. We left off discussing pouring irui kli rishon water into cold water, or cold water into kli rishon water, and we learned that, according to the Chayei Adam, when pouring cold water into hot,  the cold water needs to be added

  We are continuing in siman 3, discussing the concept of irui kli rishon. We left off discussing pouring irui kli rishon water into cold water, or cold water into kli rishon water.    The Chayei Adam writes that it is muttar to pour hot water into cold water, or cold water into hot water,

We are continuing in siman 3, discussing the concept of irui kli rishon. The Chayei Adam clarifies that the halacha we have been discussing on irui kli rishon affecting a kdei klipah worth of a food applies to a solid. If one performs irui kli rishon into a liquid, the nature of liquid is that

We are continuing in siman 3, where we learned that if one performs irui kli rishon on a food, they need to remove a kdei klipah in order to eat the food. We left off with the question of why it is necessary, even in a bedieved situation, to remove the kdei klipah, and why

We are continuing in siman 3, where the Chayei Adam is discussing irui kli rishon. We have learned that if one performs irui kli rishon on a food, they must remove a kdei klipah of that food before consuming it. We left off discussing the practical application of this case to food on Shabbos.   

We are continuing in siman 3, discussing the halachos of kli rishon. To clarify, in siman 4 the Chayei Adam will discuss kli sheini and kli shlishi, and in siman 5 he will discuss davar gush. After he discusses the level of the kli, he will discuss what foods are muttar to place inside these

  We are beginning siman 3, where the Chayei Adam will discuss the idea that a kli rishon which is off of the fire can still have the ability to cook if the temperature inside of the kli is yad soledes bo. We learned that the Yerushalmi holds that once the kli rishon is off

We are beginning siman 1. The Chayei Adam divides his sefer by klalim and simanim, rather than the traditional simanim and seifim.  The Chayei Adam writes that one who bakes bread or cooks food or samimanim (inedible dyes) transgresses the melacha of bishul.   The Chayei Adam stresses samimanim to include cooking inedible items. One may

  We are continuing in our introduction to hilchos bishul. We learned yesterday that the definition of yad soledes bo has a range, and one has to be machmir in both directions. Today, we clarify this halacha.   The lower limit is obvious, in that one cannot allow food or water to reach the minimal

We are continuing in our introduction to hilchos bishul. Yesterday, we learned about the definitions of bishul being a shinui aichus (change in the quality of the item) or a shinui tzurah (change in the form of the item).  The Gemara discusses a case of a person hardening wood by heating it in a kiln.

  Note: Welcome to our new learners! This shiur is based on the Chayei Adam. The Mishnah Berurah bases much of his halacha on the Chayei Adam, but we will note when the Mishnah Berurah diverges from the Chayei Adam. The framework of the Chayei Adam follows a clear presentation, and lends itself to learning

  We have finished siman 5, and were discussing cases in which it would be muttar to create a belilah avah on Shabbos. We learned that if the ingredients naturally mix when they are first placed together, even according to Rabbi Yosi Ben Rabbi Yehuda there is no heter to mix them together, even for
