Talmud for Terumot 4:8
רַבִּי יְהוֹשֻׁעַ אוֹמֵר, תְּאֵנִים שְׁחוֹרוֹת מַעֲלוֹת אֶת הַלְּבָנוֹת, לְבָנוֹת, מַעֲלוֹת אֶת הַשְּׁחוֹרוֹת. עִגּוּלֵי דְבֵלָה, הַגְּדוֹלִים מַעֲלִים אֶת הַקְּטַנִּים, וְהַקְּטַנִּים מַעֲלִין אֶת הַגְּדוֹלִים. הָעִגּוּלִים מַעֲלִין אֶת הַמַּלְבְּנִים, וְהַמַּלְבְּנִים מַעֲלִין אֶת הָעִגּוּלִים. רַבִּי אֱלִיעֶזֶר אוֹסֵר. וְרַבִּי עֲקִיבָא אוֹמֵר, בְּיָדוּעַ מַה נָּפְלָה, אֵין מַעֲלוֹת זוֹ אֶת זוֹ, וּכְשֶׁאֵינוֹ יָדוּעַ מַה נָּפְלָה, מַעֲלוֹת זוֹ אֶת זוֹ:
Rabbi Yehoshua says: black figs can be counted together with the white [to remove a white fig that is <i>Terumah</i> and fell into a mixture of black and white figs], and the white can be counted together with the black [to remove a black fig]. In the case of cakes of figs, the large can be counted together with the small, and the small can be counted together with the large. The round [cakes of figs] can be counted together with the square [cakes], and the square can be counted together with the round. Rabbi Eliezer prohibits this. Rabbi Akiva says: if it is known what [kind] fell in, then the one [kind] cannot be counted together with the other, but if it is not known what [kind] fell in, then the one [kind] can be counted together with the other.
Jerusalem Talmud Challah
A Genizah text has a more complete version: פתר לה בסופגנים שנעשו בחמה. ותני כן יוצאים בסופגנים שנעשו באור ואין וצאים בסופגנים שנעשו בחמה “He explains it for Bismarcks baked by the sun. It was stated thus (Tosephta Pisḥa 2:19): One may fulfill one’s obligation with Bismarcks baked on fire but one may not fulfill one’s obligation by Bismarcks baked in the sun.”; one may fulfill one’s obligation with Bismarcks baked on the fire. Does this not disagree with Rebbi Simeon ben Laqish? He explains it if the fire extends to the sides171Since the oven is much larger at the botton than in the upper part where the bread is baked, the heat comes from all sides. R. Simeon considers baking with heat coming just from one direction as cooking, not baking. In the Babli, Pesaḥim 37b, R. Simeon defines as cooking anything prepared in a vessel in the oven; he accepts as baking only what is in the oven without any vessel. This may be the same as his opinion explained here..
