The Aruch Hashulchan Orach Chaim317,4 quotes the Yerushalmi Shabbos 7,1 that suggests that there might be Borer for Humans from humans (i assume with kids who are man handled and don't move voluntarily) according to Chizkia who says that Borer applies to the same species (e.g pomegranates separated from other pomegranates), but this suggestion of Chizkia is ...

Shmiras Shabbos KeHilchasah (footnote to 3:60) quotes R' Shlomoh Zalman Aurbach that it is forbidden when the cover to the saltshaker is on. 3:60 מותר לתת גרגירי אורז (לפני שבת, ומשום אסור מוקצה) בממליחה פחותה ע"מ שיספגו את הלחות שבמלח, ובממליחה מכוסה טוב לא להוציא דרך המכסה שבה, גם אם נשאר הרבה מלח מעורב בתוך האורז footnote 179 שמעתי מהגרש"ז ...

The gemara (Shabbos 47a) explicitly permits reassembling tools that are easily and intentionally taken apart and reassembled as part of their normal use (such as fold-out beds; see also Rambam Hilchos Shabbos 22:26). Also, even a kli shemlachto l'issur (utensil devoted to purposes forbidden on Sabbath) such as a screwdriver, is allowed to be used l'tzorech ...

Shmiras Shabbos Kehilchoso (Chapter 33:4) writes that it is permitted to cut a tablet into two equal halves in order to use only half. In the footnotes (footnote 30) he quotes this in the name of Rabbi Shlomo Zalman Auerbach and explains and there is not issue of the prohibition of "Mechataich" (measuring), because the Melocha of "Mechataich" only applies ...

Cholent is considered a mixture of beans, potatoes, meat, etc. If you dip into cholent with a spoon, you are separating one glob of cholent from another glob. IOW, you are taking a mixture from a mixture. Since what you took is still mixed up, you have not performed "selection" of one type from another. So you have not performed borer at all. The Shulchan ...

http://www.dinonline.org/2010/08/10/filter-on-faucet/ Ayil Meshulash chapter 7 note 110 & Shemiras Shabbos 3:60 both say it is permitted to use a salt shaker with rice inside on Shabbos. The reasoning is because the salt shaker is made solely for immediate use, and therefore its use is not considered Derech Bereirah but rather Derech ...

Sh'miras Shabas K'hilchasah 3:78: It is forbidden to classify mixed flatware in order to organize each type into the compartment designated for it. Likewise, it's forbidden to take all the pieces of one type and dry them and then put them in their compartment. But it's permissible to put each piece of flatware into its compartment immediately after drying,...

Shemirath Shabbath, by R' YY Neuwirth (3:58), states very clearly that pouring water over tea leaves resting in a filter that is suspended over a cup, so that water passes through the filter into the cup, is not a problem of Borer. Using water cooled by transferring it to a third vessel (Keli Shelishi) is given there as an acceptable method for brewing ...

See Shabbos Kehalacha (vol. 2 12:39-42). Borer is not a problem if you don't want either thing but just want to separate them in order to dispose of them properly. (For example separating recycling from other garbage, papers for geniza from papers for garbage, Shemita fruit peels from other fruit peels to throw out). Similarly here were you don't want either ...

In Shemirath Shabbath Kehilchatah 3:56 a. One may use a water tap fitted with a filter. b. If the filter becomes detached, it may only be replace on Shabbath in a provisional manner ant fixed on tightly, since this may fall within the prohibition against construction. I should mention that I heard elsewhere that this mainly applies to water that is ...

My understanding is that it is not Borer (separating) in accordance to how SA Horav explains in Hilcos YT (500:18) the reason why Nikkur (separating the forbidden fats and veins from an animal) is permitted on Yom Tov, thogh it may appear like Borer (separating), is because really it's all one Min (species) with the meat it's just that the Torah forbade that ...

Of course CYLOR, but the short answer is yes. The longer answer is look in Hilchos Yom Tov siman 510 siff two and three with the Mishna Berurah and Biur Halacha. Basically any Borer you can't do before Yom Tov due, for quality purposes, is allowed to be done on Yom Tov. So coffee which is only good fresh is allowed to be prepared in a way that ...

I found in a Sefer "Toras HaShabbos Chelek Alef" (a modern day kitzur Sefer that he addresses this point. See Perek 15 on Hilchos Borer Footnote 102 (towards the end.) He writes that seemingly it should be ossur to remove the rock so why does the SA allow this. He says that could be the reason is is because the person is not m'cavain (doesn't have the ...

I'd say there's no problem because you can't pick the connected hair. Borrer is when you pick the Psolet (or what you don't want) out of the food (what you do want). It's like picking a shoe that happens to be in the middle of a row of other shoes that are nailed to the floor. A more Talmudic could-be-proof, is from Mishna Beitza 23a: רבי יהודה אומר אין ...

Mori WeRabi, Harav Mansour Shelit"a holds that it is Mutar to use a water filter on Shabbat providing that the water is drinkable without the filter. source

On the Hebrew Wikipedia entry for Borer, several opinions are cited for those of the opinion that Borer does not apply by non-food items (see footnote #7): 1) מהר"י עייא"ש בשו"ת בית יהודה - Mahari Ayash in "Sheilos v'Teshuvos Beis Yehuda" 2) האור שמח בפירושו על הרמב"ם - Ohr Sameach in his commentary on the Rambam 3) See Sefer Minchas Yaakov 2:...

You could find the appropriate combination of stringencies to make it a problem: Kalei Habishul - if you would hold like the Mishna Berura (318:42) that we suspect everything of being kalei habishul (cooking even in a kli sheni) unless it is explicitly identified as otherwise. Kli shlishi - if you would hold like the Chazon Ish that there is no such thing ...

Synopsis of ideas from Jewish Pathways: If your flatware is already separated by type in a storage drawer / box (many people do this), then, there is no issue of borer. There is no issue of borer if the table is set immediately prior to eating the meal. Citing Shu"t Igrot Moshe Orach Chaim 4:74:11, if one wants to set the table ahead of time, he may ...

A general idea used throughout Shulchan Aruch is that The Torah does not forbid "derech achilah". This means that if through the normal act of eating, which is from the point of lifting the food until it is chewed and swallowed, you happen to perform something that can be called a melachah, that is generally not forbidden. For instance, grinding is one of ...

Here's my take on it: Borer is the act of sorting (anything, not just food). Bishul is the act of cooking. Both are prohibited on shabbos. Then there's an act called eating, which is (obviously) permitted. When you "sort" food in a permitted way (as @sam mentioned in the comments), then this is no longer considered an act of borer, but rather an act of ...

Shmiras Shabbos K’hilchasa (3:35 and note 97): He brings down that it is mutar to remove the stems from tomatoes, plums, apples, pears, peaches, and cherries as long as this is done for immediate use. He brings down two possible rationales for this. a) The stem is just like a peel that is preventing you from eating the entire fruit. According to this ...

In the Sefer Ashrei Ha'ish it brings from a Sefer Pischei halachos that borer does not apply to a person. It states the following: “מותר להוציא פירורים או חוט מהזקן ואין נקרא בורר כי לא שייך בורר באדם״ . Translation: it is permitted to remove crumbs or a string from ones beard and it is not called borer for borer is not possible regarding people. I seem to ...

Shulchan aruch Orach chaim 319: היו לפניו שני מיני אוכלים מעורבים בורר אחד מאחד ומניח (השני כדי) לאכול מיד: הגה: ושני מיני דגים מיקרי שני מיני אוכלים ואסור לברור אחד מחבירו אלא בידו כדי לאכלן מיד אף על פי שהחתיכות גדולות וכל אחת נכרת בפני עצמה אבל כל שהוא מין אחד אף על פי שבורר חתיכות גדולות מתוך קטנות לא מיקרי ברירה ואפילו היו שני מינים ובורר משניהם ביחד ...

The first question is already answered but you ask for more details on borer and muktze. Overall they do not represent obstacles to using such a knife. There is no issue of borer when selecting the good from the bad, in this case the tool you want from the others, with the hand, right before use. Shemirat Shabbat KeHilchata (3:27) notes it is permitted to ...

According to Star-K article, no: Since many people enjoy their tea mainly on Shabbos, it would be appropriate to briefly mention the do’s and don’ts of tea preparation on Shabbos. One should not use tea/herbal bags or loose teas on Shabbos. This is because tea is part of that group of foods known as kaley habishul, or easily cooked foods. These ...

The Baal HaTanya, in his Piskei HaSiddur, Hilcheta Rabbata L'Shabbata, rules that one should remove a fly from cup of wine by spilling out the wine until the fly leaves the cup. Since he is holding the cup of wine, and want the wine and not the cup, this is considered manually separating Food from Waste, which is permitted on Shabbat, if one wants to ...

Shulchan Aruch Orach Chaim 319,1 specifies how to do borer on Shabbos permissibly: ואם בירר בידו כדי לאכול לאלתר מותר: Only if he separates with his hands (not with a specialized instrument) for eating straight away is permitted. In the Rema Orach Chaim 319,1 explains the meanig "straight away": הגה: וכל מה שבורר לצורך אותה סעודה שמיסב בה מיד ...

Rav Shlomo Zalman Auerbach in תיקונים ומלאוים to the Shemiras Shabbos Kehilchasa (הערה ר ד״ה לפני עכ״ד) permits “marinating” the food even the night before if, by doing that, it would enhance the taste of the food. It would be permitted as it is called דרך אכילה - the normal way of eating. The idea here is that there it is muttar to prepare the food סמוך ...

I had a similar question. My case was about doing borer to take out frozen challa from the freezer (in a case where that could be borer) long enough before the se'uda so that it could defrost. (This would seem to be even more meikel than your case, as it is ochel mi'psoless). I heard from a local Rav that this is mutar. However, if it takes 4 hours to ...
