I emailed another lady about this ?, but am getting braver about posting a new thread. I made a batch of sourdough today, used 1 cup bread flour, 1 cup milk and 1 cup sugar. . .it said to cover it and let it set on my counter to let it breathe, so its been breathing for over two hours . . . now what do I do, refrigerate it? I had a batch years ago, and I know I kept it in the fridge, but I need a little jolt of memory help!!!
