Shabbat 76B

הכא נמי, חזיא לדוגמא.

Here too, since these substances are suited to be piled together in the sample of a merchant seeking to sell them, they join together with regard to carrying out on Shabbat as well.

מתני׳ המוציא אוכלים כגרוגרת ⁠— חייב, ומצטרפין זה עם זה מפני ששוו בשיעוריהן. חוץ מקליפתן, וגרעיניהן, ועוקציהן, וסובן, ומורסנן. רבי יהודה אומר: חוץ מקליפי עדשין שמתבשלות עמהן.

Mishnah: One who carries out a measure of foods fit for human consumption equivalent to a dried fig-bulk into a domain where carrying is prohibited on Shabbat is liable. And all those foods join together with one another to constitute that amount because they are equal in their measures. This amount is calculated without their shells, and their seeds, and their stems, and their bran, the husk that comes off of the wheat kernel when pounded, and their coarse bran that remains in the flour. R' Yehuda says: None of the shells are calculated, except for the shells of lentils, which join together with the lentils to comprise the measure for liability because they are cooked and eaten with them.

גמ׳ וסובן ומורסנן לא מצטרפין? והתנן: חמשת רבעים קמח ועוד, חייבין בחלה הן וסובן ומורסנן! אמר אביי: שכן עני אוכל פתו בעיסה בלוסה.

Talmud: The Talmud asks: And do the bran and coarse bran of cereals not join together? Didn’t we learn in a Mishnah: Dough made from 5-quarters of a log of flour and a bit more obligates one to separate ḥalla? That amount includes them, the flour, and their bran, and their coarse bran. Apparently, bran and coarse bran join together with the flour to constitute the requisite measure. Abaye said: Bran joins together with the flour with regard to ḥalla and the making of bread, since a pauper eats his loaf made from dough mixed with bran. However, with regard to carrying out on Shabbat, the food items in question must be suitable for all people, since the measures are small and are calculated by their significance.
