Tired of oil-and-vinegar-type salad dressings separating? This sounds weird, but works great: Just spray a little bit of pan coating spray (like PAM) into the mix. Most of those sprays are made of lecithin, which is a natural emulsifier, and helps to bind the dressing ingredients.
Great idea! I'm going to try that someday! BUT I will spray the Pam into my vinegar and oil dressing when I am standing OUTSIDE.
NOTE: We have discussed the dangers of PAM and similar sprays before on this web site.
