When you think of the pretzel, there's not a whole lot to it. They're pieces of knotted dough, baked with loads of salt on them, sold for next-to-nothing at movies, sporting events or other spectator-friendly areas where one wants to walk (or sit)-and-much. They are also occasionally served with mustard. But, that's your grandpa's pretzel. Nowadays, pretzels are showing up all over the place, most popularly in bun-form, but sometimes even in the occasional dessert. So today, on National Pretzel Day, we celebrate with a gallery of L.A.'s best use of the salty dough.
