Listen "Bishul Shiur 19 (Final Shiur) & Laws Of Fast Days"
Episode Synopsis
Part 1: Bishul (conclusion):1- Recap of the position of the Kol Bo (regarding stirring and removal with a spoon while the food is on the fire) from last Shiur.Recap of the Halachos of covering a pot as discussed last week. 2- other considerations with regards to hastening the cooking of food:(1) If you know the food isn’t fully cooked, according to all shitos it would be prohibited to return the cover the pot since by containing the heat it hastens the cooking process. Same would apply regarding the closing of the oven door (assuming there are no other issues with that), if there is food in the oven not fully cooked. (2) Food on a “Blech” where the food is not directly above the fire, rather slightly to the side, and the food isn’t fully cooked, and one wants to move the food closer to the fire, that would be prohibited since it is hastening the cooking. (3) A hot water urn that the water that did not hit temperature before Shabbos, one may not remove water from it since removing the water hastens the cooking process since it now contains less water to boil.Part 2 (14:08 into audio):Laws of a fast day:Brushing your teeth and rinsing your mouth out:Gemara B’rachos regarding tasting food on a Taanis (vs. eating) that tasting is permitted. Rishonim- this is referring to a private fast (of an individual), but for a public fast even tasting is prohibited. Shulchan Aruch- Only on Yom Kippur and Tisha B’av is tasting prohibited. ReMA- the prohibition to taste applies to all fasts. Explanation of the Shulchan Aruch (Vilna Gaon)- Initially the fasts (other than Yom Kippur and Tisha B’Av) were optional, therefore they were dependent on our acceptance and therefore not included in the prohibition of tasting. The definition of tasting is not swallowing (according to all that is prohibited), rather it is putting something in ones mouth and then spitting it out. BaCH- the shiur that it is permitted is a Re’viis. Rinsing your mouth out seemingly would be permitted according to the Shulchan Aruch. However the Shulchan Aruch elsewhere says that it is not proper to rinse ones mouth out on a public fast day. Magen Avroham and others differentiate that it is only problematic when it is more that a Re’viis, less than a Re’viis would be permitted. Beis Yosef in the name of the Trumas HaDeshen- 2 reasons why it is permitted to rinse on a Taanis Yachid: 1- your intention is to rinse and not to derive pleasure; 2- the prohibition of tasting more than a Re’viis is by liquids other than water. The Levush, the Aruch HaShulchan and others say that this doesn’t apply to a public fast is because we’re concerned that you may come to swallow. The Mishna Beturah is lenient if one finds it difficult as long as you are careful not to swallow (i.e. bending your head down and not gargling). And the same was done by the MaHaRIL as described by the Be’er Heiteiv. One can also consider the position of the Shulchan Aruch as a combination to be lenient. Some poskim say it is better to use mouthwash (than water) since it is not considered edible.
