What would be the bracha on "bread" that had mashed fruit or vegetable kneaded into the dough, but tastes like bread? For example, if you mashed a few potatoes into the dough, then the bread will still look and taste very much like regular bread after it's done. Is using mashed fruits/vegetables different than [making bread out of fruit juices][1]?
