# There is a rabbinic prohibition not to return cooked food to a fire on [[Shabbat]] even if the food is fully . Some say that the reason for the prohibition is that it looks like cooking and some that it is because one may come to stoke the coals. <Ref>

* The Mishnah (Shabbat 36b) records Beit Hillel’s opinion that one may not return a pot to a Kirah (type of stove meant to hold two pots) on Shabbat if the Kirah is heated with pressed sesame or wood unless the coals were covered with ashes or removed.

* Rashi Shabbat 36b "lo machzirim" says its "mechzay kimivashel", meaning, that the reason Chazal prohibited placing fully cooked food on the fire on Shabbat is that it looks like one is cooking on Shabbat. Baal HaMoar 16b, Rashba (38b D”H MeKlal) in name of some geonim, Ritva (40b D”H VeAskina), and Ran (17b D”H Bei Rav Ashi) write that the prohibition of Chazara is a gezerah of Chazal because it looks like cooking when one heats up cold food on [[Shabbat]]. Mishna Brurah 253:55 quotes this Ran.

* Rav Mordechai Willig (Am Mordecahi p. 48) writes that one may heat up cold fully cooked solid food on an electric hotplate which is not used for cooking and has only one temperature setting. Halachos of Shabbos (p. 313), Shabbos Kitchen (p. 43), and Chazon Ovadyah (p. 78) agree. See Sh”t Igrot Moshe 4:74:35 who rules that if it is impossible cook on a particular electric hotplate, one may heat up already warm food on it if it has only one setting. Shemirat Shabbat KeHilchata 1:30, however, rules that an electric hot plate is a like a covered fire and one may not return food onto it without fulfilling the other conditions of Hachzara. Rabbi Belsky (quoted by Halachically Speaking 4:16:3) and Orchot Shabbat (p. 99) agree.

* Chazon Ovadyah ([[Shabbat]] 1 pg 55) holds that since Chazara is only forbidden as it looks like cooking a plaata (electric hotplate) which isn’t used for cooking should be permitted for Chazara. Rav Frankel (Kol Torah (Iyar 5723, Sh”t Har Tzvi O”C 136, Toldot Zev ([[Shabbat]] 2 pg 234)) concurs. Sh”t Igrot Moshe (O”C 4:74(35), 1:93) permits Chazara on a blech if the food is fully cooked because it’s not used to cook and being a blech for [[Shabbat]] it serves as a reminder it’s [[Shabbat]]. Sh”t Yashkil LeAvdi O”C 7:28, Rav Shlomo Zalman Aurbach (Shulchan Shlomo 253:27), Sh”t Tzitz Eliezer 8:26, Chukei Chaim Peretz 8 in name of Rav Sheinberg, Sh”t Me’oneh Lashon 22, Sh”t Shemesh UMagen (3:54(3) in retraction of his stringent opinion in 1:53), Sh”t Tefilah LeMoshe 1:32, and Yitzchak Yiranen (pg 50) concur to permit Chazara on a plaata. However, Yashiv Moshe (Rabbi Twersky pg 36) in name of Rav Elyashiv and Sh”t Avnei Yishfeh 1:83 are strict because a plaata is sometimes used to cook. </ref>

* Rav Soloveitchik (cited by Rabbi Jachter in “Hachzara and Hatmana”, koltorah.org) ruled that one may rely on the Ran. (This ruling of Rav Soloveitchik is also recorded in [http://books.google.com/books?id=XDzlvJ5zsfsC&pg=PA91&lpg=PA91&dq=rewarming+food+on+shabbos+the+rav+soloveitchik&source=bl&ots=zGIQw2Rkng&sig=3aiB2mMukVfevkvDRG94ziTvueY&hl=en&ei=TOuqToa3C6PW0QGO4uyEDw&sa=X&oi=book_result&ct=result&resnum=4&sqi=2&ved=0CDQQ6AEwAw#v=onepage&q&f=false Halakhic positions of Rabbi Joseph B. Soloveitchik, (Rabbi Zeigler, vol 4, pg 90-1) and by [http://www.tzemachdovid.org/thepracticaltorah/vayakhel.shtml Rabbi Michael Taubes].) This is also relying on the Gra’s opinion that only liquids need to be warm. Rav Mordechai Willig (Am Mordechai p. 47), however, rules that initially one should not rely on this lenient ruling. Rav Hershel Schachter (“Hilchos Bishul B’Shabbos”, min 52-5), Shemirat Shabbat KeHilchata 1:23, 39 Melachos (Bishul #203), and Halachos of Shabbos (p. 355) agree.
