A good par baked and properly frozen par baked roll is very difficult to discern from a fresh baked version of the same roll. It really depends on your source for the baked goods and the equipment you use to finish bake. Its a very good alternative to purchased full baked breads, when you have a very uneven service. Baking par baked takes a short amount of time, can be done in small batches and I can pretty much guarantee it will yield a product superior to purchased rolls. But it depends on the source, if your buying big box store par baked crap then crap in crap out. If you find a good baker that has formulas set up for par baking its a very good option. Many good deli's use par baked products.
