QUESTION: Besides for cooking and baking, what other types of food
preparation are prohibited on Shabbos but permitted on Yom Tov?
DISCUSSION: The following types of food preparation are permitted
Tov-- provided that the food will be used on that same Yom Tov day [or, if
Yom Tov falls on Friday and an eiruv tavshilin was made, for Shabbos]. It
is permitted to:
Peel eggs, fruits or vegetables at any time (not only just before
mealtime) and without restriction, either with a knife or with a peeler.(1)
Debone chicken, fish or meat.(2)
Remove melon or fruit seeds from the melon or fruit.
Vegetables may be diced, either with a knife or a vegetable dicer.(3)
Grind or mash cooked potatoes, onions, bananas or apples, even with a
grater or a masher.(4)
Sort cutlery in order to set the table.(5)
Oil, mayonnaise or other liquids can be added to egg or tuna salads
any other food mixture without restriction.(6)
Prepare instant potatoes or baby cereal.
Squeeze excess oil out of canned tuna or fried fish [not only just
Prepare whipped cream or mayonnaise, using either a fork or a rotary
Make pudding, jello, ice cubes,(8) or salt water.(9) L'chatchilah,
food items should be prepared before Yom Tov.
QUESTION: Do the majority of contemporary poskim permit smoking on
DISCUSSION: No, they do not. In the past, there were conflicting
whether or not smoking is permitted on Yom Tov. The general principle of
Hilchos Yom Tov is that Kindling is permitted not only for cooking or for
lighting candles, but also for any activity which is "common and
beneficial to most people." Years ago, when smoking was commonplace and
socially and medically acceptable, some poskim viewed it as being
a "health benefit" and permitted it on Yom Tov. Other poskim prohibited it
even in those days. Today, however, when the dangers of smoking are well-
known and documented, smoking can no longer be classified as a "common
activity", and is, therefore, prohibited even according to the opinions
who permitted it in past generations.(10)
QUESTION: On Shabbos [or Yom Tov], is it permitted to use suntan
order to prevent sunburn?
DISCUSSION: Suntan lotion which is in cream, ointment or thick,
pouring oil form, is forbidden to be used on Shabbos, as it may be a
violation of the Shabbos Labor of Smoothing.(11) It is permitted, however,
to use suntan protection which is in a liquid spray form, since Smoothing
does not apply to runny, non-viscous liquids like liquid spray.
Although there is a Rabbinic injunction against taking medicine on
Shabbos, suntan protection is not considered medication, since its purpose
is not to heal but to protect. It is similar to using insect repellent on
Shabbos, which is permitted since its function is not to heal but to
Taking medication for ordinary sunburn, however, even if it is in spray or
liquid form, could be a violation of the rabbinic injunction against
taking medicine on Shabbos. In the atypical case where the sunburn is so
severe that one feels "weak all over" or bad enough to require bed rest
because of it, liquid or spray medication is permitted.(13)
Note: Our discussion regarding suntan protection pertains to those who
might get sunburned while fulfilling a Shabbos mitzvah, e.g., those who
need to walk a long distance to shul on Shabbos. But to deliberately sit
in the sun in order to get a suntan is not in keeping with the spirit of
Shabbos, and indeed, is forbidden on halachic grounds by some contemporary
QUESTION: What is the correct procedure to follow regarding washing
hands on Shavuos morning after remaining awake all night?
DISCUSSION: The widespread custom of staying awake the first night
Shavuos to study Torah presents a halachic problem - what to do about
washing the hands and reciting the blessing of al netilas yadayim. The
following background information will help us understand the problem and
its solution: The Rishonim offer two basic reasons for the Talmudic law
(15) of washing our hands in the morning and then reciting the proper
The Rosh tells us that washing is necessary because a person's hands
move around in his sleep and will inevitably touch some unclean part of
The Rashba says that since each one of us becomes a biryah chadashah -
a "new person" - each morning, we must sanctify ourselves anew in
preparation to serve Hashem. This sanctification is similar to that of a
kohen who washes his hands before performing the avodah in the Beis ha-
[In addition to these two reasons, there is still another reason for
washing one's hands in the morning - because of ruach ra'ah, the spirit
of impurity that rests on one's body at night and does not leave the hands
until water is poured over them three times(16). Indeed, touching various
limbs or organs of the body is prohibited before hand-washing, due to the
danger which is caused by the spirit of impurity.(17) This third reason
alone, however, is insufficient to warrant a blessing,(18) since a
blessing is never recited on an act which is performed in order to ward
Does one who remains awake all night long need to wash his hands in the
morning? If we follow the Rosh's reason, then washing is not necessary,
for as long as one remains awake he knows that his hands remained clean.
If we follow the Rashba's reason, however, washing may be required, since
in the morning one becomes a "new person," whether he slept or not.(20)
[In addition, it is debatable if the spirit of impurity that rests on the
hands is caused by the nighttime hours - regardless of whether or not one
slept - or if it rests upon the hands only during sleep.(21)]
Since this issue remains unresolved, the Rama suggests a compromise:
washing is indeed required, as the Rashba holds, but a blessing is not
recited, in deference to the view of the Rosh. Not all the poskim agree
with the Rama's compromise. In their view, the blessing should be recited.
(22) Since we again face a difference of opinion, it is recommended that
one of the following options be exercised:
One should listen - with intent to be yotzei - as another person, who
did sleep, recites the blessing.

20 The rationale for this is: 1) Lo pelug, which means that once the Sages
ordained that washing the hands is necessary because one is considered
a "new person", they did not differentiate between an individual who slept
and one who did not (Beis Yosef quoted by Mishnah Berurah 4:28); 2) The
blessing was established to reflect chiddush ha-olam, which means that
since the "world" as a whole is renewed each morning, it is incumbent upon
the individual to sanctify himself and prepare to serve Hashem each
morning; whether he, personally, was "renewed" is immaterial (Beiur
Halachah quoting the Rashba).
