Challah1: 4
אֵלּוּ חַיָּבִין בַּמַּעַשְׂרוֹת וּפְטוּרִים מִן הַחַלָּה: הָאֹרֶז, וְהַדֹּחַן, וְהַפְּרָגִים, וְהַשֻּׁמְשְׁמִין, וְהַקִּטְנִיּוֹת, וּפָחוֹת מֵחֲמֵשֶׁת רְבָעִים בַּתְּבוּאָה. הַסֻּפְגָּנִין, וְהַדֻּבְשָׁנִין, וְהָאִסְקְרִיטִין, וְחַלַּת הַמַּשְׂרֵת, וְהַמְדֻמָּע — פְּטוּרִין מִן הַחַלָּה.
These [items] are liable to tithes but are exempt from challah: rice, millet, poppy, sesame, legumes, and less than five reva'im in [the case of] grain.  Sufganin, duvshanin, iskeritin, a pan loaf, and dimua mixtures are exempt from challah.
Challah1: 5
עִסָּה שֶׁתְּחִלָּתָהּ סֻפְגָּנִין וְסוֹפָהּ סֻפְגָּנִין — פְּטוּרָה מִן הַחַלָּה; תְּחִלָּתָהּ עִסָּה וְסוֹפָהּ סֻפְגָּנִין, תְּחִלָּתָהּ סֻפְגָּנִין וְסוֹפָהּ עִסָּה — חַיֶּבֶת בַּחַלָּה; וְכֵן הַקְּנוּבְקָאוֹת חַיָּבוֹת.
A dough which is sufganin at its beginning and sufganin at its end is exempt from challah. [If] it was dough at its beginning and sufganin at its end, [or] sufganin at its beginning and dough at its end, it is obligated in challah. And kenuvkaos are likewise obligated [in challah].
