Shulchan
Aruch Chapter 253: The Law of Putting Pots On A Double Stove and
A Single Stove on Erev Shabbat
(5 Paragraphs)
REMA in Brackets []
Introduction
to this chapter: One of the forbidden acts of labor on the
Sabbath is cooking. In order to eat hot food on the Sabbath, Jews
prepare food on Friday and leave these foods on the stove to continue
cooking on Shabbat. Until modern times, there were two types of
stoves used for cooking. One was a Tanur, which was a stove with
a single opening on top, where one pot was
placed. The interior of the stove was heated with wood or other
items, and one could also place items in the oven itself. Since
all of the stove's heat was concentrated in one
spot, it was considered a very hot stove. Another type of stove
was a Kirah, or a double stove. This had two openings on top for
two pots. The interior was also heated with wood or other
items. This was not a very hot stove. The Rabbis at the
time of the Mishnah were concerned that on Shabbat, perhaps a person
may
accidentally stir up the embers in the oven in order to produce more
heat so that the item will cook better. So, to prevent this from
happening, they enacted restrictions on what type of stove one may use
on the Sabbath to keep food on, what foods may be put on, what the
stove can be heated with, and how the heating elements may be modified
for use.
