Today I discovered a 1/4-full bottle of pure maple syrup had gotten moldy, so searched this site and came across this question: Should maple syrup be stored in the refrigerator?Should maple syrup be stored in the refrigerator?
My follow-up question is: Will there be any ill effects (such as altering the flavor or changing the molecular structure such that it's dangerous to eat, etc) from repeatedly heating maple syrup for serving, and re-cooling in the fridge?
If so, I'll try to only heat as much syrup as I'm likely to use at a time, although this will be more hassle, naturally :)
