1. The Central Axiom
סחיטה (squeezing) is a toldah — of דש when squeezing a fruit (extracting juice as one extracts grain), of מלבן when wringing a cloth. The criterion for fruits: their usual use — olives/grapes (juice) = assur mid'oraisa; citrus (per custom) = mid'rabbanan. And: juice squeezed on a solid food (mashkin habain le-okhel) is permitted.
2. Key Concepts
| Concept | Definition | Application |
|---|---|---|
| סחיטה | To squeeze, extract liquid | Toldah of dash or melaben |
| מפרק | "To detach" liquid from solid | The name of the toldah |
| משקין הבאין לאוכל | Juice designated for solid food | Permitted — juice is "absorbed" |
| סחיטת בגד | Wringing a wet cloth | Assur mid'oraisa (melaben) |
| דרך הפרי | Usual use of the fruit | Determines severity |

5. The Lemon: Destination of the Juice
The most subtle case — and the most frequent in a Shabbos kitchen — is that of the lemon. It concentrates all the logic of the siman: one and the same fruit can be permitted or forbidden to squeeze, not according to its nature, but according to where the juice ends up.
a. The liberating principle: משקין הבאין לאוכל
Squeezing juice is only assur (toldah of דש) when one extracts a liquid meant to be drunk or used as a liquid. But when the squeezed juice is immediately absorbed by a solid food, halacha considers it "coming to the food": it does not become an autonomous beverage, it is swallowed within the solid. Squeezing has not produced a liquid — hence the permission.
b. The three destinations of lemon juice
- On a solid food (fish, salad, piece of meat) → juice is absorbed → permitted: it is mashkin habain le-okhel.
- Into a liquid (tea, water, a beverage) → juice joins a liquid and reinforces it as a drink → assur: a beverage has been produced.
- Into an empty vessel, to collect it as is → this is the act of squeezing in its purest form → assur.
c. The edge case: squeezing onto sugar
What about squeezing lemon on sugar, which absorbs it, but with the intention of then dissolving everything in water? The immediate action falls under mashkin habain le-okhel — sugar is a solid that absorbs. But since the ultimate purpose is to make a beverage, many poskim are machmir: what counts is not only the first material destination, but also the intended use. The criterion "destination of the juice" must therefore be read at two levels: the food receiving, and the use intended.
6. Mnemonic "סמ"ב"
ס — Sechitah (סחיטה) — squeezing: toldah of dash / melaben.
מ — Mashkin le-okhel (משקין הבאין לאוכל) — juice on food = permitted.
ב — Beged (סחיטת בגד) — wringing a cloth = assur mid'oraisa.
— The more a fruit is designated for juice, the more serious squeezing it.
7. Pitfalls to Avoid
8. Modern Practical Cases
| Situation | Conduct |
|---|---|
| Squeezing an orange / grapefruit | Assur — prepare juice before Shabbos |
| Squeezing lemon on fish / salad | Permitted (mashkin habain le-okhel) |
| Squeezing lemon in tea | Assur (becomes a beverage) |
| Wringing dishcloth, sponge, cloth | Assur mid'oraisa |
| Eating a juicy fruit with a spoon | Permitted (derech achilah) |
| Wringing wet hair | Assur (sechitah) |
9. Final Summary Table
| Element | Detail |
|---|---|
| Subject of the siman | The melocho of sechitah — squeezing on Shabbos |
| Number of seifim | 20 |
| Mishnah Berurah | 59 entries |
| Talmudic source | Shabbos 143b-145a ("sochtin b'pagei'in") |
| Nature | Toldah — of dash (fruits) or melaben (cloth) |
| Fruit criterion | Olive/grape = Torah; mulberry/pomegranate/citrus = rabbinic; others = permitted |
| Practical decision | No fruit juice; no wringing; lemon on food = permitted |
10. The Practical Commandments of Siman ש"כ
Squeezing on Shabbos — the checklist
- Do not squeeze fruits usually squeezed (citrus) — prepare juices before Shabbos.
- Lemon on a solid food = permitted; in a liquid = assur.
- Never wring / squeeze a cloth, sponge, wet rag.
- Eating a juicy fruit (with spoon, full bites) = permitted.
- Wet hair: do not wring.
- In doubt (pickle, preserve) → consult the Rav.
