<<Disclaimer: Verify this information before applying it to your situation.>> I make my own vinaigrette dressing because there are many things I can't eat and because I'm also on a rotation diet. But when I just mix the vinegar and oil together it isn't that nice "creamy" stick-to-the-lettuce kind of dressing that I used to enjoy. So, I tried adding some xanthan gum, as little as about 1/16 of a teaspoon to 1 cup of combined liquid, and what I got was stringy kinds of globs that looked pretty terrible. Anyone tried this combo and been successful? I know that xanthan gum has pretty potent thickening attributes, so a very little goes a long way. Does guar gum or something else work?? Thanks, Nancy
