Hi there! Last month, I made some homemade vanilla sugar with fresh vanilla beans and sealed it up in a glass jar to season for a few months. Since the only lid I had was of questionable quality, I sealed the top of the jar with Press & Seal wrap and then screwed the lid on top of that.
Today I went to check my vanilla sugar and give it a good shake, but it had all clumped together and so I removed the lid and Press & Seal to stir it and noticed that there is a faint, off smell to the sugar. I can definitely smell the vanilla, but there's another, uglier scent there too, one that I can't quite put my finger on, but it's not nice.
What can I do? Is there a fix to this or do I have to scrap it all? Please help!
