1 The Laws of Food Prepared Erev Shabbos in order to complete on Shabbos, containing 9 Seifim: Although it is permitted to do She’hiya [leaving a pot on the stove over Shabbos] with raw meat, this refers to {meat cooked} in a pot, but placing meat for roasting next to a fire close to Shabbos is forbidden, since it it roasts quickly and one might stir the coals. However, this is only for beef or goat meat; but kid or fowl, cut up into sections, are permitted (to be placed next to a fire for roasting). We do not fear that the coals might be stirred, since such meat will burn (i.e., go beyond the stage of roast and become burned meat) if the coals are stirred, for they require no more than the heat of the fire. However, (if roasting is done) in an oven whose mouth is sealed with clay, then even a whole kid or fowl, as well as beef or goat meat are permitted. We need not fear that anyone will stir up the coals, for if the stove will be opened for stirring air will enter, cooling the stove and causing the meat to harden and spoil. Rema: There is no difference here whether it is completely raw or somewhat cooked. [Beis Yosef]. As long as the body (of the animal) is whole, even if its head or feet are not attached to it, it is considered whole (Hagahos Mordechai). There are some who are stringent and hold that everything is permitted in a stove that is sealed with clay, and, (on the other hand) everything is forbidden over an open fire. The distinction made between a kid and fowl and other meat, exists only where the mouth of the oven is closed but not sealed with clay. Common practice is in accordance with this opinion (Tur, Hagahos Ashiri, Beis Yosef in the name of Rashi, the Smag, the Smak).
