Rashi says the fruit was mixed with leaves and by spreading it out on the table the fruit separated from the leaves automatically.
Why according to Rashi is there a potential issue of borrer?
Is this the same explanation of Tosfos?
Learn מהרש”א who asks on Rashi – Why is it permitted to scatter the contents causing the fruit to become unmixed. Why isn’t this considered Borer as the objective of Borer was accomplished – separating the fruit from the leaves?
Is this also a question according to the Ramban?
Halachic Conclusion:
Is it permitted to cause a mixture to become unmixed by scattering the mixture?
We have finished the Hachzara sugiya, but I still have a few questions on halacha lemaase, would it be possible to cover them?
I would like to discuss a few of these questions this week
1. When the oven is working on Shabbos (the oven is in Shabbos mode and the controls are covered), there is hot air coming out of the exhaust at the back of the oven. Is it allowed to put the food over the exhaust, or the exhaust opening has the status of kira which is not grufa vektuma?
2. What is the minimum depth of the pot which we turn upside down on the blech to put food on it?
3. Is there a maximum size of the pot which we turn upside down? For example, can it be a commercial baking pan that covers the whole blech?
4. Stam pot without food in it is muktze, correct? If yes, should the pot that will be turned upside down to put food on it be designated before Shabbos, or any pot can be used?
5. Can food be placed directly on blech far from the fire, where it is not yad soledet bo?
6. Can food be placed directly on blech not over the fire, where it is yad soledet bo?
As well as the questions below
The prevalent practice is to use a blech on a stovetop which would serve as קטום. What is the source that a sheet of metal would accomplish the same halachic status as placing ash on the coals?
See שולחן ערוך אורח חיים ס’ רנ”ג סע’ ג and משנה ברורה ס”ק פא
In many electrical appliances the heating elements are covered by a sheet of metal like a crock pot which the walls of the crock pot covers the coils. Does one need to cover/line the crock pot or is the sheet of metal/ walls considered a blech?
May one move a pot which is placed on the blech in an area which is not directly over the fire to a part of the blech which is directly over the fire?
Is the entire blech considered a stovetop which is גרוף וקטום or is it considered just סמוך לכירה?
