I have some grade B maple syrup I got from a farmers market. I stupidly didn't realize it should be refrigerated after opening and it's been in my pantry for a month or so opened (I swear as a kid we never put our maple syrup in the fridge!!). This developed a thin mold skin on top. How safe is it to skim the mold off, strain it, boil it, put it into a glass jar in the fridge and continue to use? It's hard to get maple syrup where I am so really hoping I can salvage it!!
