Last year at the local grocery I chanced upon a sourdough starter packet, and decided to buy it. Months later, I finally had some time to put it together. I put the container on the back burner of the stove, and baked something so that the heat would come up through that burner and keep the container nice and warm. Too effective. I killed the yeast, but I gave the mess about two days to really start stinking before I admitted instantaneous defeat. The yeast of my soul felt killed too.
So last week, on Friday, I started a new sourdough sponge. From scratch.
