I made mulled cider in the crockpot for a gathering yesterday. Last evening, I unplugged it, thinking I would let it cool, pour it back into the jug the cider came in, and then refrigerate it. Instead, I forgot about it and went to bed. I discovered it 12 hours after I unplugged it. Unsure of what to do, I turned the crockpot back on high for the last 2 hours. Is it safe to keep the cider or should I throw it out?
