We have a small specialty shop and would like to make pretzel rolls for sandwiches and such.  We would like to use with pre made or par-baked dough.  

• Is there a good source for pre-made or par-baked dough for pretzels/bagels that can be formed into rolls?
• Would like to have the lye white dough that is seen in the ny begels we have here, is there a commercial source for that? frozen/par baked?
• Does the oven type matter? regular commercial or convection? steam?

We would prefer to not make the dough from start since we do have space limitations at the location we are in but would be able to boil dough and bake.

this is the style we are looking for.  

Thank you
