I've heard it said, on this site and elsewhere, that bread-making is not a strength of American cuisine, and I tend to agree. France, Italy, Germany and Russia put the US in the shade when it comes to bread-making. Having said this, is there any single distinctly American bread that you'd put up against that of the continental powers? I'd offer true San Franciscan sourdough as the great American bread. The one that could go toe-to-toe when it comes to dough.
Any other nominations?
