I made these rolls for dinner tonight.  OMG they smell so good, I can't wait to dig in!  Click on  Bun Recipe to view the link.  They are "marketed" on the original post as bread bowls...  I tried that a few months ago and found that it didn't work that well... partially because I used whole wheat flour which made them very dense, and partially because I didn't make them big enough.  Tonight, we are having them with burgers!  So I feel really confident that they are going to be a huge hit!
