I'm assuming you are talking about steak which has been processed under rabbinical supervision. Presently, in th US, with the exception of liver, all meat is salted to remove problematic blood by the certifying agency before it hits the stores and restaurants. So meat which is edible does not have to be cooked "enough" and rare is fine.

Per the OU Daf HaKashrus Volume 15 No 6 dated March 2008 this question was answered by Rabbi Gersten as follows "In a near sea level environment water boils at 212 degrees Fahrenheit. at higher elevations water boils at lower temperatures. In Denver for example the average boiling temperature is 202 degrees Fahrenheit. when Hagalah is performed in high ...

What Monica answered above, that it is 'meat juice'. To find out in much greater detail about this, see here: No matter what the source of the issur, the Ran asks: We clearly observe that blood continues to come out of meat even after the salting process is over. Indeed this blood is sometimes even redder than the blood that was originally expelled. ...

Rabbi Moshe Tendler says that the principle of "as it absorbs, so it exudes" (k'bol'o kach polto) means METHOD of absorption, not temperature. Fire kashering for things that became unkosher through dry heat (roasting, grilling) and boiling for liquids. His example was that a spoon that became unkosher on a camping trip to the Dead Sea through immersion in ...

Piskei Teshuvos (227:2) cites Bircas HaBayis who says that the blessing can only be recited during the quake or within 2-3 seconds (תוך כדי דיבור) after it's over. He also says (from Teshuvos Shevet HaKehasi) that even mild quakes warrant this blessing, and (from Shaarei Teshuvah in the name of Maharam Chaviv) that if another quake occurs even that same ...

The source for all the melachos comes from the actions done to build (or operate) the Mishkan. Writing was used to make symbols on the boards that made up the outer walls. They were used so that when the Mishkan was disassembled and reassembled they would know which boards went where. Two letters (one on each board) were used to mark which boards matched ...

The Talmud searches for Beit Shammai's reason on Kiddushin 11a. The first suggestion, that of Rav Zera, is that an average woman thinks she is important enough to not accept anything less an dinar for kiddushin. The gemara asks, according to this, it should be completely subjective based on the individual girl. The answer is that this rule applies in a case ...

The Mazal Sha'ah on the Rambam infers that the shi'ur l'chayyev for anointing with t'rumah oil is a k'zayis, based on R' Yehudah's opinion in the gemara (K'risus 6b) who holds that a person is liable for a k'zayis of prohibited anointing with the shemen hamishchah (Commentary to Mishneh Torah, Hil. T'rumos 10:2). (One should note that it is still Biblically ...

Chabad says that what's left in the meat after it's been kashered is juice, not blood, and ok. No sources cited, though I've heard this from a number of people (for what that's worth).

Rashi to that verse, and Tosafos in Bechoros 5a (s.v. Esrim), ask this question. They answer (based on the Targum of the verse) that there were actually separate measuring utensils that had to be made in the listed denominations. See there for the detailed explanation of what each one was used for. Update: Here is how it is presented by D.A.F. Resources: ...

I believe for most Halachic topics today that require "one prutah's worth" of cash, goods, or services (e.g. the minimum needed to effect a wedding), we go with an economic definition: the smallest amount of money that can buy something. Despite inflation, there are plenty of things you can still buy today for fifty cents or less, so fifty cents is certainly ...

There was a small amah (5 tefachim/amah) medium amah (6 tefachim/amah) 2 large amahs (6t/a + half a finger-breath & 6t/a + a whole finger) According to R. Yehudah, the temple building was measured by the 6t/amah and the vessels are all measured by the 5t/amah. According to R. Meir, the 6 tefach amah was used everywhere except the gold alter, and ...

The Mishna Brura in OC 1 says: י"א דלענין זה אמרינן כולא ביתא כד' אמות דמי אבל אין לסמוך ע"ז כ"א בשעת הדחק. "There are those who say that with regard to this (washing hands), we say that the entire house is as 4 amos (cubits), but one should only rely on this when forced." The Aruch HaShulchan in OC 4 says: מפני שיש מחמירים ומזהירים ע"פ הזוהר שאסור לילך ...

The weight of a p'ruta was half that of a barleycorn, and it was silver. Assuming — without justification — that barleycorns weigh now what they did then, and other unjustified assumptions, we have: Wikipedia gives the weight of a barleycorn as about 65 mg. At about 31,103.4768 mg per troy ounce and a current price of silver of about USD28.20, that gives ...

There is a famous machlokes whether kzayis is a volume or weight measure. Many sefardim follow the Kaf Ha'Chaim that it is a measure of weight. http://www.vbm-torah.org/pesach/pes62-yr.htm ...As the Maggid Mishneh explains, the Rambam here establishes that these measurements are determined by volume, not weight, a principle that seems to emerge as well ...

Excellent question. Leviticus Ch. 12 says that it's 7 days if the baby is a boy, and 14 if a girl; (but she has to then immerse in mikvah, a ritual bath). (Then there's a lengthier stretch of time that she can't enter the Temple, but is permitted to her husband.) However: Skip ahead to Leviticus Chapter 15. If a woman has a normal period (15:19) then she ...

Some base the Kadish for the soul on the date of death. Others say it goes from the date of the burial (See Pnei Baruch 34:9). The amount of time a soul should have the kadish is the 12 months of geihinom. The minhag is to retract this to 11 months so that it doesn't appear as if the son is assuming his parent needed geihinom (Rema YD 276:4). I have ...

Normally kiddush requires a "reviis", which we'll call 3.3 fluid ounces. Kiddush (for shabbos day, as well as havdalah) may be recited on any chamar medina, "beverage of the land, which you'd serve a respected guest." In addition to wine/grape juice, this certainly includes: Beer (found in the Gemara) Apple juice (This appears in the Artscroll "Radiance ...

The Gemara in Pesachim 46a (brought in the Rambam Laws of Chametz 5:13 and the Shulchan Aruch OC 459:2) says that if one leaves dough for the length of time that it takes to walk 1 "mil" (a Talmudic unit of distance) then it becomes Chametz. Opinions regarding the time it takes to walk a mil vary from 18-24 minutes, and here we are strict to take the shorter ...

As for your third point, the Aruch HaShulchan (OC 3:10) and the Mishna Berura (OC 3:31) both rule that it is permissible to delay until one can find an appropriate place to relieve oneself. Additionally, the Mishna Berura explicitly includes all other cases of Kavod Habriyot (human dignity) in this exception.

There are a lot of answers being presented, some decent and some, no offense guys, seriously lacking and/or confusing. What they all have in common, though, is that they all leave out (though YDK's mentions it somewhat vaguely) the fact that cooking has nothing to do with the Kashering process. Yes, we could get technical and discuss ways to roast meat in ...

"Ad delo yada" is not accepted as halachah at all. (Taz, Orach Chaim 695:2) It means to drink enough that you sleep, and then you don't know the difference between "cursed is Haman" and "blessed is Mordechai." (Maharil, cited in Rema there) Which is the greater benefit that Hashem granted us: that Haman was degraded and executed, or that Mordechai was ...

From the Tur (Orach Chaim 46): It is from a braisa based on pesukim. According to Natronai gaon, David haMelech set it into halacha to stop the deaths of 100 Jews daily where the spiritual cause of there death was unknown until "he delved and understood with ruach hakodesh and fixed" the 100 brachos. So, it an obligation and is brought so in the Shulchan ...

The Talmud (Shabbat 91a) discusses the minimum measurement of food that must be carried between domains on Shabbat in order to be obligated in punishment. The minimum shiur depends on what the intended use of the object is. A kegrogeret (the size of a dried fig, which is greater than or equal to a kezayit) is the minimum amount of food when the food is ...

This might simply have been a confusion of units. Sizes.com claims that a Russian verst is equal to 500 sazheni, but a Moscovy verst is 1000 sazheni. The sazhen was fixed at 7 English feet (2.134m) in both systems way back during the 1700s in Peter the Great's rule. In 397:1, the Aruch HaShulchan says that specifically, he is talking about the Russian ...

Actually, according to Yoreh De'ah 66:10, your own Human blood is only Assur because of Maris Ayin (similar to fish blood). Therefore: If it's still in your own mouth, and it doesn't leave, you may swallow it. If it leaves your mouth, you may not swallow it Also, if it gets on food (e.g. you're biting into a sandwich), you may not eat it (i.e. the blood on ...

http://www.star-k.org/kashrus/kk-mitzvos-maakeh.htm The ma'akeh does not have to be a solid wall, but any spaces should be sufficiently narrow that a child cannot fall through. The ma'akeh should be sufficiently sturdy that it will hold back a person who falls against it.

From Menachos 43b It was taught: R. Meir used to say, A man is bound to say one hundred blessings daily, as it is written, "וְעַתָּה, יִשְׂרָאֵל--מָה יְהוָה אֱלֹהֶיךָ, שֹׁאֵל מֵעִמָּךְ" - "And now, Israel, what does the Lord your God require of you?" Rabbi Meir uses a play on the word מָה, saying instead - מאה. In effect, this then translates to - "And ...

A fire is a fire is a fire - See OH 673(1) ואע"פ שאין השמנים נמשכים אחר הפתילה ואין האור נתלה יפה באותם הפתילות Even though the wicks don't absorb the oil well and the light [fire] doesn't attach well to those wicks (--translation mine) (i.e. even if your lights are poor, your still yotzeh the mitzvah).
