OMG! I saw Emeril Lagasse on Good Morning America last week. He made an incredible con queso dip!!!! It was so wonderful sounding that I made it myself and ate it, despite the fact that it had 2 T of flour in the recipe. It was heavenly; I can't remember when I had something so wonderful. And I didn't use the homemade corn chips as he suggested, but dipped raw cauliflower in it. If I had some guar gum, I would thicken it with that. Maybe you have something you thicken things with. Or, I would be tempted to leave it out and go on.

I hope the link works, otherwise just go to Good Morning America's site. It's still on their "front page" near the bottom.
