Countless burger threads that touch on this, but I want to start fresh. To me, a burger with a crap bun isn't a burger, it's a patty atop two plates. Yet for all our savvy about gourmet burgers, packaged storebought crap is still the rule rather than the exception. What are the best buns you've ever had, buns that really enhanced the whole? Or buns you've never had but think would be great?
