I have been making bean salad for a long time. Recently I mixed together the vinegar, oil, sugar and black pepper for the dressing, and put it in a pint sized canning jar with 2-pc lid and refrigerated it, intending on making in the next day or so, but it never happened.
I still have this nice dressing in the refrigerator, and am wondering about food safety - all the ingredients are fine for long periods unrefrigerated, so there should not be a food safety issue, right? I'm also wondering about staleness. I don't want to use it to make bean salad, and have a less-than-wonderful salad. I hate to throw out perfectly good food. Can anyone help me?
