Vixmom, to answer your question from last night: I used sourdough from the local grocery and it was terrible. San Antonio is a tortilla town, not a bread town. People here seem to hate character in or crusts on their bread. They want everything soft and characterless. So, there was no sour flavor and the bread seemed to fall apart the moment you touched a knife to it. It was sloppy and messy, but it did not get in the way of the cheese or the butter.
