As I mentioned at the start of this subject, there are so many varieties of bread produced around the world, I would just highlight the ones most common to the Americas and parts of Europe and Canada; Canada because it is known to be the "breadbasket of the world" due to its seemingly unending wheat fields and immense production of said wheat.

Adding sugar or other sweeteners or spices to the basic formula gives us such staples as donuts, cakes, pie dough, cookies etc., etc. But these are not commonly recognized as bread so I haven't highlighted them under this subject.
I'm currently researching desserts and will at least mention the sweet dough products, but I am amazed at what I'm learning about desserts of the world and I am sure that you will be also.
