Halacha Orach Chaim 168

Most flour product that one recites a Mezonos on we refer to as Pas Habah Bekisnin. These are products that require Hamotzei and Birchas Hamazon if an abundance is eaten, as explained in our last post.

There seems to be a difference of opinion what exactly Pas Habah Bekisnin is.

The Rashba, Tur and others say it is a bread product filled with fruit, nuts or other delicacies. This is similar to Rugalach and Kakush cake.
The Rambam rules Pas Habah Bekisnin is a bread product with a large proportion of other foods intended to alter the bread from tasting like regular bread. This is similar to honey cake, chocolate cake and lemon cake, although the primary example of this, would be a cake made from dough rather than batter.

The Aruch rules that Pas Habah Bekisnin is a bread product that is brittle, like saltines and crackers.

Meimer Mordechei writes that it is likely that these three opinions are all in agreement with each other. We therefore apply the Halachos of Pas Habah Bekisnin to all of them.

The Chazon Ish categorizes, that bread products mixed with other ingredients will only be defined as Pas Habah Bekisnin if there is enough added where most people would consider it cake, rather than bread.

There are food manufacturers that market bread products, like Mezonos rolls. They add apple juice or other liquids instead of water to give them this definition. Based on this Chazon Ish, it is safe to assume that a Mezonos roll is in essence an oxymoron. This is because the apple juice added is not intended to make it a product similar to cake. On the contrary, apple juice is only added to the extent that it will not harm its bread like character. Mezonos rolls are therefore no different from regular rolls, and Hamotei should be recited.
