Arukh HaShulchan, Orach Chaim 317:19-27

Sugya Map

• Issue: The definition of Borer (Sorting) regarding Ochel mitoch Psoles (selecting food from waste) when multiple items are considered "food."
• Nafka Mina: Can one choose the "better" items if the "worse" ones are still edible?
• Primary Sources: Shabbat 74a, Shulchan Aruch, Orach Chaim 317:1, Arukh HaShulchan, Orach Chaim 317:19-27.

Text Snapshot

• Leshon: "וכל זמן שהם מעורבים, הרי הם כשני מיני אוכלים..." (Arukh HaShulchan, Orach Chaim 317:20).
• Nuance: The Arukh HaShulchan emphasizes that the definitional status of Psoles (waste) is subjective to the user's immediate intent. If both are edible, the act of removal is not "sorting waste" but "choosing a preference," which complicates the heter of Ochel mitoch Psoles.

Readings

• Mishnah Berurah (317:28): Argues that if one desires the better portion, the inferior portion is considered Psoles. Thus, selecting the best is permitted.
• Arukh HaShulchan (ibid): Takes a more lenient, holistic view. He posits that if both are edible, the label "Psoles" is inherently weak, and the prohibition of Borer relies on a clear distinction between usable and unusable matter.

Friction

• Kushya: If Borer is a melacha of Tikun (rectification), why does the subjective intent ("I want this one, not that one") define the psoles?
• Terutz: The act is defined by the state of the mixture. If the items are distinct types (e.g., peas and carrots), selecting one is Borer. If they are the same type, selecting the "good" from the "bad" is permitted only because the "bad" is considered psoles—but if both are "good," the heter is arguably inapplicable.

Intertext

• Compare with Shulchan Aruch, Orach Chaim 319:1 regarding Dosh (threshing) vs. Borer. The Arukh HaShulchan frequently bridges the yishuv between the Rambam and the Rosh.

Psak/Practice

• Heuristic: When selecting items of the same species, do not leave the "inferior" items in a state of unfitness. One should consume the desired portion immediately, as the heter of Borer is strictly limited to le'alter (immediate use).

Takeaway

The prohibition of Borer is not merely about separating, but about the creation of a refined state; if the item is already "food," your preference does not magically turn the remainder into "waste."
