I've found that mixing distilled white vinegar and brown sugar makes a great salad dressing. It reminds me of that strawberry vinegar salad, with almonds.
Just use a spoonful or two of brown sugar; add to taste, rather.
This also works well for a fish stick dip.
I originally tried this with rice vinegar, and while I thought it tasted great, it had a funky smell (it doesn't have the smell with distilled white vinegar).
