I hadn't used my sourdough starter in... months. Maybe once this summer I refreshed it and baked with it. I was sure it was a goner, but for the heck of it I took it out of the fridge last night, poured off the hooch, scooped off the gray slime on the top, and took a spoonful. I refreshed it and left it on the counter overnight. Sure enough, this morning it was bubbly and lively, so I went ahead and tried baking with it. It was a little bit sluggish, kinda like I feel after waking up from a too long nap, but it still did its job.
