Interesting that he's using the vitamin C tablet, though from reading the King Arthur book, it sounds like increasing the acid level will increase sour flavor. It can also lead to flat bread, and since leaving the starter in the fridge overnight is how King Arthur recommends increasing the acid level, my new theory is that by refrigerating my dough, I inadvertantly increased the acid to a point where the yeast could no longer function.

Goddammit, I'm going to have to start keeping pH strips in the kitchen, aren't I?
