Halacha - Brachot
Submitted by Adam  Answered by Rav Peretz Moncharsh
Question: Does the rule (for Ashkenazim) of always saying minei bsamim at havdala apply even when smelling the bsamim outside of the strucure of Havdala al HaKos (eg they were unavailable at the time of havdala)?
Answer: An excellent question. The Magen Avraham proposes the source of the minhag is based on many people not being familiar with the intricacies of different berachos on various fragrances, and we don't want someone to become confused in the middle of havdala. Based on this reason, Shmiras Shabbos K'Hilchaso proposes that the minhag should not apply in precisely the circumstance you mention. However since other seforim suggest other reasons for the minhag which may apply even when smelling the besamim separate from the rest of havdala, he leaves the issue unresolved.

Halacha - Mug that changes colour on Shabbat
Submitted by Ahuva  Answered by Rav Peretz Moncharsh
Question: I bought a personalized mug and had a picture and words printed on it. The thing is that this mug doesn't show the picture or writing until you pour boiling water in it. Can such a mug be used on Shabbat if your intention is not necessarily so that you can see the picture. Thanks.
Answer: It should not be used hot on Shabbos.

Halacha - kinetic watch
Submitted by ilan flax  Answered by Rav Peretz Moncharsh
Question: are kinetic watches allowed to be worn on 3 day yom tov
Answer: While a mechanical self-winding watch may be worn on Shabbos or Yom Tov as long as it has not stopped running, even though the spring will be tightened. However the same does not apply to a "kinetic" watch where the movement of the wrist generates electricity that recharges the watch's battery and may not be worn at all on Shabbos or Yom Tov.

Halacha - "Break-Apart Ices"
Submitted by anonymous  Answered by Rav Peretz Moncharsh
Question: The ices that children eat that you break them apart and at the area of breakage the ice is exposed encased in plastic tubing- is this mutar to 'break-apart' on Shabbos?
Answer: Yes, it is permitted because one may tear on Shabbos to access food and you are not creating a kli because the empty tube will be disposed immediately on finishing the ices and not reused.

Halacha - Shabbos
Submitted by Tzvi Schneider  Answered by Rav Peretz Moncharsh
Question: Lichvod Harav: If somebody has dishes that he uses only for Shabbos..... would he be allowed to wash them on Shabbos, for next Shabbos(since, maybe, there is no 'Hachono' from Shabbos to chol) ?
Answer: It would not be allowed, because one also may not prepare on one Shabbos for the following Shabbos.

Halacha - Shabbos Clock/Timer
Submitted by anonymous  Answered by Rav Peretz Moncharsh
Question: I live in Israel and I use shabbat timers which has on/off pins which go one way for on and the other way for off. If I put my Shabbat Platta on a timer which goes on twice a day (evening before the evening meal and morning before the morning meal), can I extend the off time after the timer goes off during the day, by moving the ON pins to OFF, which the whole timer/clock is still in the electric outlet? Thank you.

Reb Shlomo Zalman Auerbach allowed one to change the setting on a Shabbos clock to keep an appliance that is currently off from turning on, because it does not cause a fire to be extinguished just never to light. However many Poskim disagree. Additionally, Reb Moshe Feinstein was concerned that moving the pins is muktza. So while there are grounds to be lenient, it is advisable not to.

However a couple of side points. Where to you keep your cholent overnight if the platta is off? Also, what are you putting on the platta when it comes on in the morning and how? Wet, cold foods may not be placed on the platta at all, and even dry foods may only be placed on an intervening pan according to most opinions.

Halacha - Talis for Kiddush?
Submitted by anonymous  Answered by Rav Peretz Moncharsh
Question: I have noticed some people who continue to wear their Talis after Shachris on Shabbos day to their home. When they are ready to make Kiddush they cover their head with the Talis. Where does this come from? Is it a minhag, halacha?

There is reason in Halacha to cover the head for kiddush out of respect for the beracha, however a hat would certainly suffice.

Halacha does not require one to wear a talis for kiddush, but some Chassidim have such a minhag. The is a Pesikta that writes one should fulfil "zachor es Yom HaShabbos l'kadsho" through "atifa" which usually refers to the talis. This pasuk is the same one used to derive the obligation for kiddush. Therefore the Minchas Eluzur of Munkatch wore his talis for kiddush in the morning, but the Rebbes of Satmar and Sanz did not. Since this is an issue of minhag, one should follow the custom of his father.

Halacha - Different size challos
Submitted by anonymous  Answered by Rav Peretz Moncharsh
Question: I once read that one should make different size challot and to make the one for Shabbat day larger than the one for Friday night since it is a more important meal. How serious is this? Because we tend to eat more bread on Friday night (since cholent is filling in itself) and I therefore usually use the bigger ones for Friday night?
Answer: You hit the nail on the head. While there is a concept to make the day challa bigger, it is not necessary to go hungry by night or to throw away extra challa after the day meal. In my house we have the same issue and generally use the bigger challa at night. Alternatively you could make two small challos for night and eat both of them, and only cut one large challa in the morning.

Halacha - medicine on shabbas
Submitted by anonymous  Answered by Rav Peretz Moncharsh
Question: Is adderal mutar on shabbat? the only reason i want to take it on shabbat is because it is hard for me to focus and i would be able to learn a lot more torah.

First of all it should be clear that Adderall is a Schedule II drug under the Controlled Substance Act and is a violation of Federal law to take it without a prescription from a physician. Amphetamines can have serious side effects and lead to addiction, and the Torah does not expect you to significantly risk your health for the sake of learning. I will assume you are taking this potent drug under the consultation of a qualified and reliable doctor.

Regarding Hilchos Shabbos; while generally medicines may not be taken on Shabbos, however this only applies when they are treating an ailment. A pill that is being used to enhance performance is not included in the issur and therefore it seems to be mutar similar to a caffeine pill. However, since Adderall is primarily used to treat ADHD, which may be considered an illness, it is not so clear. An additional lenient factor in your case would be that some Poskim permit taking any medicine for a mitzva, although most do not. Ideally the extended release form of Adderall could be taken before Shabbos begins, and there would be no issues of Hilchos Shabbos.

Halacha - Shalosh Seudos Erev Rosh Chodesh
Submitted by David  Answered by Rav Peretz Moncharsh
Question: Is it necassary to finish Sholosh Seudos before Shekiah on erev rosh chodesh?

It is not necessary to finish the entire meal before shkiya, but if one eats bread after sunset there is a dilemma whether to say Retzai or Ya'aleh v'Yavo, so it best to at least finish the challa before shkiya.

Halacha - Shabbat Platta
Submitted by anonymous  Answered by Rav Peretz Moncharsh
Question: I am used to using a blech in America. Now that I've made aliyah, i've noticed that every frum family I've been invited over for Shabbos uses a Shabbat Platta instead of a blech. I would like to understand how a Shabbat Platta is permitted for use on Shabbos day. I learned from my Rabbi that one should only put cold dry food on the area that is warm and not Yad Soledes Bo. When I see frum families warm cold food on the Shabbat Platta durign the daytime that were taken out of the fridge, the cold food became "hot" even on another layer of metal over the platta. I think the additional layer over the platta might be extremely hot to the touch. How is this permitted on Shabbos? Please explain. I would like to continue using a blech that I'm used to from America, but a frum family said that gas is more expensive than electricity and that it might run out on Shabbat, so they prefer to use the Platta. Thank you!

Let's start with the practical issues, the main practical difference between a blech and a platta is that the platta is a single uniform temperature over the entire surface while a blech can have hotter and cooler spots. So a platta is more predictable, but a blech gives you more options. Regarding the cost, I don't think the difference is significant, and in any event Shabbos expenses are refunded by Hashem

Regarding the Halacha issues, raw food may certainly not be cooked on Shabbos, whether on a bleach or a platta. Food may be placed on either before Shabbos begins, because the only issue is that we are concerned if one placed raw food on a fire shortly before Shabbos that he may become impatient and stoke the flame on Shabbos. With an electric platta that has only a single, unadjustable heat setting this is not an issue, and a blech is considered an unusual manner of preparing food that would remind one not to adjust the heat. The remaining issue is, as you mentioned, reheating cold, dry precooked foods on Shabbos, where actual cooking does not apply since it is already cooked, and we have already determined that stoking the fire is also not an issue with either a platta or a blech. However there is an additional prohibition of doing an action that appears to be cooking. Since a platta is designed and suitable only for reheating and not for cooking, some Poskim permit placing cold dry precooked foods directly on a platta and consider it more lenient then a blech which is on the stovetop, which is the normal location for cooking. According to the more stringent opinion a platta is identical to a blech, but there is still a solution to place the food you want to reheat on top of an upturned empty pan. This avoids any problem of appearing to cook. It must be emphasized and made completely clear that this only helps if the food is both dry and completely cooked before Shabbos.

Halacha - Shabbos belt
Submitted by anonymous  Answered by Rav Peretz Moncharsh
Question: Dear Revach rabonim, are there any poskim who allow to wear shabbos belt for keys on the tie or shirt? What are the best possible or halachically acceptable ways to wear such belts. If possible please cite the sources where I can look it up inside. The reason why I am asking this question is because I saw Igros Moshe on this topic where he explicitly forbids doing so. So, I was wondering if there are poskim on the level of hoRav Moshe zt'l who allow to wear such belt on tie or shirt. My second question: is it acceptable for a rov to pasken on his own against deos of Igros Moshe in case where no major poskim (like rav Moshe) offer different psak on the matter? Thanx very much, Dovid

The accepted Halacha is that the key must serve a functional purpose to be permitted and not just be attached or even decorative. I have seen a belt buckle where the key is attached in place of the prong that is inserted in the hole in the leather belt, and this is ideal.

A Rav would have to be very big or have very clear sources if he wants to permit something Reb Moshe forbade and none of his contemporaries disagreed. So it is unlikely, but it is possible.

Halacha - ovens with timers
Submitted by anonymous  Answered by Rav Peretz Moncharsh
Question: Firstly, kol hakavod for your impressive site! If one has an oven which has a timer, can one leave in it before Shabbos food that was 1/3 (or 1/2) cooked which will continue cooking on shabbos and then the oven will turn off automatically? The light doesn't go on when you open the door. Thanks so much!

There is no problem leaving the food in the oven if it is half cooked and edible, however when you open the oven door to remove the food there is a strong likelihood that the thermostat will immediately ignite the oven. Ideally the timer should be set to turn off the oven shortly before you anticipate wanting to remove the food on Shabbos. If this is not practical, you should only open the oven door when the fire is already on, and you will at worst be indirectly causing it to remain lit for longer but not igniting it on Shabbos.

Halacha - Internet Purchasing motzei Shabbat
Submitted by anonymous  Answered by Rav Peretz Moncharsh
Question: Can a person living in Israel purchase merchandise from an American based online merchant while it is still shobbas in America on the chashash that a Jew might do work cfor you? Thank You

It is permitted because one may assume that the person one is buying from is from the majority of the population, which in the US is not Jewish.
