My DH came home and hurt my brain last night by sharing a story from work. My daughters and I make homemade sauces, jams, etc. that he sometimes sells at work. He keeps a selection in his cube and his workmates will stop by and see what's "in stock".
Well, yesterday one of his co-workers stopped by to pay him for some jam she picked up last week while he was out of the office. He asked her if she liked the jam? Well, yes, it was okay at first. But after a day or two it got really watery. Well, we like happy customers so he offered her the opportunity to bring it back and get a different one.
She was very happy to be able to get a replacement, and brought the yucky jam back to him. At which point he just had to ask, "Um, did you put this in the refrigerator once you opened it?" No, she had not. Was that necessary? She had opened a jar of homemade jam and kept it in her cube over the weekend. DH said it was full of mold. I asked him why she would think refrigeration was unnecessary for *any* kind of jam, let alone homemade, but he just shook his head. Made his brain hurt, too.
