I got home and the babysitter had left the jug of maple syrup (the real stuff) out on the counter today without the top on. It's supposed to be refrigerated - what do you think? I'm generally a stickler about food going off/refrigeration, etc...but am thinking it's not meat/dairy/eggs, so maybe it's not so iffy?
Yeah - I'd say it's fine. I think the sugar content is high enough that it keeps very well. I don't always put my m.s. in the fridge, if I want it more room temp. FWIW, it may grow mold that way, and you can skim it off, boil it, and call it good as new.
