I've tested Hidden Valley Ranch (packet mix), turned black.
Yep, everything white or thick got that way courtesy of mr. starch. grrrrrrrrrrrrrrr
I bet you could make any of them yourself though, just leave out the bad guys. I've been eating a lot of Newman's Own Balsamic Vinagrette (sp?). Don't take my advice though, I'm not pain free yet, just "reduced" so far.
