Chapter 41: 7-10
The Laws of Hamotzi7. One should not throw the portions of the bread on which hamotzi was recited when distributing them to those assembled, for it is forbidden to throw bread. One should place it on the table before them rather than hand it to them.
8. It is a mitzvah to break bread on the most important loaf one possesses. Accordingly, if one has both a whole loaf and a portion of a loaf of the same species of grain, and one desires to eat from both within the meal, one should break bread with the whole loaf, for it is considered more important. This applies even if the whole loaf is smaller than the cut loaf and made from coarser flour.
However, if the whole loaf is made from an inferior species of grain - e.g., it is from spelt while the cut loaf is from wheat - one should recite the blessing over the loaf from wheat, even it is smaller.
Nevertheless, if the whole loaf is of barley and the cut loaf of wheat, a person who fears G-d should also give deference to the loaf of barley. Even though barley is inferior to wheat, it is still explicitly mentioned in the verse (Deuteronomy 8:8) which describes the produce of Eretz Yisrael. Furthermore, this loaf is whole. What should he do? He should place the cut loaf beneath the whole loaf and cut them both at the same time.
If both loaves are of the same species and both are whole or both are cut, one should recite the blessing over the one made with the finer grade of flour. If both are made with the same quality flour, one should recite the blessing on the larger one.
9. A person who does not refrain from eating bread baked by a gentile (see Chapter 38) [should still show deference to bread baked by a Jew]. If he has before him both bred baked by a Jew and bread baked by a gentile, he should recite the blessing over the former, provided both loaves are whole or both are cut and both are equal size and of the same species of grain. If the bread baked by the Jew is of coarser quality of flour, one may recite the blessing on whichever one he desires.
If a host himself refrains from eating bred baked by a gentile, but brings it to his table for a guest, he should remove it until after reciting the blessing hamotzi.
10. All the above principles relating to giving precedence to the most important loaf apply only when one desires to eat from both of them at this meal. However, if one desires to eat from only one loaf at this meal, he should break bread with the loaf he desires. No attention is paid to importance.
