Similarly, [if] one consecrated his fruits before they reached the tithing stage, and redeemed them, they are obligated. [If he consecrated them] after they reached the tithing stage, and he redeemed them, they are obligated. [If] he consecrated them before they were finished, and the Temple clerk finished them, and afterward [the owner] redeemed them, they are exempt, since at the time of their [potential] liability they were exempt.

[If] a non-Jew gave [ingredients] to a Jew to make a dough for him, [it is] exempt from challah. [If] he gave it to him as a gift, [if] before he had thoroughly mixed [it], it is obligated [in challah]; but [if] after he had thoroughly mixed it, it is exempt.  [If] one makes a dough [together] with a non-Jew, if [the portion] of the Jew does not consist of the minimum measure for challah [liability], it is exempt from challah.

[Regarding] a proselyte who converted and had a dough, [if] it was made before he converted, he is exempt [from having to separate challah]; but [if it was made] after he converted, he is obligated [to separate challah]. And if it is uncertain [when the dough was made], he is obligated [to separate challah]. But one is not liable on its account to [the penalty of] a “fifth.”  R' Akiva says: Everything follows the formation of a crust in the oven.

[If] one makes a dough from wheat and rice, if it has the taste of grain, it is obligated in challah, and one can discharge his obligation on Pesach with it. But if it does not have the taste of grain, it is not obligated in challah, and one cannot discharge his obligation on Pesach with it.
