The Shulchan Aruch (Siman 253) permits leaving a dish on the fire at the onset of Shabbos (shehiyah) and returning it during Shabbos (chazarah) when there is no fear of stoking the fire: a fully cooked dish, a heat source that is garuf v'katum (coals removed or covered), a pot still hot, held in hand, with the intention to return it, and placed on top and not inside.
The Rema rules like the lenient view (cooking to the level of maachal ben Drusai is enough) and the custom is lenient for chazarah on our hotplates. For a concrete case, ask your Rav.
Siman 253 deals with two distinct acts: leaving the pot on the fire on Friday (שהייה, shehiyah) and returning it on Shabbos after removing it (חזרה, chazarah). The underlying concern is always the same: שמא יחתה — lest one stoke the fire. That concern falls away when the dish is already cooked and the source is garuf v'katum (coals removed or covered) — which today is exactly what an unregulated hotplate achieves. For a concrete case — ask your Rav.
On Friday night the cholent simmers on the blech; on Shabbos afternoon you lift the pot to serve, then you would like to set it back. Two acts, two questions. They feel thoroughly modern — hotplate, Shabbos-mode oven, slow cooker — yet the Shulchan Aruch already codifies them, in Siman 253 of Hilchos Shabbos (Orach Chaim), speaking of the kirah (low stove) and the tannur (oven).
What does the Shulchan Aruch say in Siman 253?
The Mechaber (Rabbi Yosef Karo) devotes seif ב to chazarah — returning the pot during Shabbos:
כִּירָה שֶׁהִיא גְּרוּפָה וּקְטוּמָה וְנָטַל הַקְּדֵירָה מֵעָלֶיהָ — אֲפִילּוּ בְּשַׁבָּת מוּתָּר לְהַחֲזִירָהּ כָּל זְמַן שֶׁהִיא רוֹתַחַת, וְלֹא הִנִּיחָהּ עַל גַּבֵּי קַרְקַע. וְדַוְקָא עַל גַּבָּהּ, אֲבָל לְתוֹכָהּ אָסוּר.
"A kirah that is swept and covered (garuf v'katum) from which one removed the pot — one may return it even on Shabbos, as long as it is still boiling hot, and one did not set it on the ground. And specifically on top — but inside it is forbidden."
The siman in fact opens with shehiyah (seif א), then develops chazarah (seif ב), and in the following seifim the techniques of handling on Shabbos. The single thread throughout: removing the fear that one might stoke the fire.
The two questions: shehiyah and chazarah
| Act | Meaning | When? |
|---|---|---|
| שהייה (shehiyah) | Leaving the pot on the fire on Friday so it keeps heating during Shabbos | Before Shabbos |
| חזרה (chazarah) | Returning to the heat source a pot one had removed from it | During Shabbos |
| הטמנה (hatmana) | Wrapping the pot in insulation that adds heat (codified in Siman 257) | Before / during Shabbos |
The 3 axes of shehiyah
1. שמא יחתה — the fear of stoking
The engine of the whole siman: we fear that in trying to speed the cooking of a dish not yet ready, one might stoke the embers — a labor forbidden on Shabbos. Wherever that fear falls away, shehiyah becomes permitted again.
2. גרוף וקטום — coals removed or covered
Removing the coals (garuf) or covering them with ash (katum) reduces the heat and signals that one does not intend to stoke. On a modern appliance, a hotplate with no adjustable thermostat — whose power one cannot raise — plays this role.
3. The state of the dish
A dish that is fully cooked and would only spoil by staying on the fire — or a dish entirely raw that one leaves until the next day — gives no incentive to stoke. It is the in-between case (half-cooked, or cooked but still improving) that requires garuf v'katum.
The 5 conditions of chazarah
To return a pot during Shabbos, the Mechaber and the Rema together set five conditions:
| # | Condition | Why |
|---|---|---|
| 1 | A garuf v'katum source | Otherwise one is suspected of wanting to stoke |
| 2 | Pot still hot (רוֹתַחַת) | Otherwise it would be a fresh cooking |
| 3 | Held in hand, not set on the ground | The act must remain continuous |
| 4 | Intention to return it from the outset | One has not "broken" with the fire |
| 5 | Placed on top, not inside, and dish cooked כל צורכו | "Inside" is forbidden even on garuf v'katum |
Sephardim and Ashkenazim: the Rema's nuance
The Mechaber rules first like the Chachamim: to leave a half-cooked dish, one needs garuf v'katum. The Rema (Rabbi Moshe Isserles, for Ashkenazim) concludes "ונהגו להקל כסברא האחרונה" — the custom follows the lenient view: a dish cooked to the level of מאכל בן דרוסאי (half-cooking) is enough. He also reports that one is lenient for chazarah in "our ovens," which have the status of a kirah, even if one set the pot on the ground — as long as it has not cooled.
Customs therefore differ between communities — hence the importance of knowing your own minhag.
Modern application: hotplate, Shabbos-mode oven, slow cooker
- The hotplate (blech): with no power adjustment and, where relevant, covered with a metal sheet, it corresponds to a garuf v'katum source — hence the leniency for shehiyah and chazarah of an already-cooked dish.
- The Shabbos-mode oven: the siman recalls that the tannur is stricter than the kirah; "Shabbos mode" seeks precisely to neutralize any adjustment.
- The slow cooker: depending on its construction (covered element, no accessible setting), several authorities liken it to a garuf v'katum kirah — with important nuances.
Contemporary authorities rely on this framework to discuss our appliances — with differences depending on the minhag, the type of hotplate and the state of the dish's cooking.
This article presents what the source says for the purpose of study. It does not rule on any practical case. To know whether your hotplate, oven or slow cooker conforms — depending on your community and your situation — ask your Rav.
Frequently asked questions
May you leave a dish on the hotplate before Shabbos begins?
Siman 253 permits it (shehiyah) when there is no fear of stoking: a fully cooked dish, or a garuf v'katum source. An unregulated hotplate serves as garuf v'katum. For a concrete case, ask your Rav.
May you return a pot to the hotplate during Shabbos?
That is chazarah. It is permitted on garuf v'katum under five conditions: dish cooked, pot still hot, held in hand, with the intention to return it, and placed on top and not inside. Customs differ — ask your Rav.
What is garuf v'katum?
A stove from which the coals have been swept out (garuf) or covered with ash (katum), which removes the fear of stoking. A hotplate with no thermostat, covered with a metal sheet, plays this role today. For practice, ask your Rav.
