I boiled my brining solution last night for our turkey (2 cups cost plus world market turkey brine and 1 gallon of water) around 7:30pm last night and took it off the heat to cool on the counter. By the time we went to bed it was still fairly hot, so I was going to set an alarm in a couple of hours to get up and stick it in the fridge. I slept through my alarm and it's now 5:30am and it's been out on the counter (with a pot lid) for 10 hours. Is it still safe to use? It was only the brine mix and water, nothing else.
