I'm with you Carol. I'm allergic to onions, and if you think corn is ubiquitous, try onions! It's usually not even on the label, but instead appears in the nebulous ingredient "spices."

Only one cure for it, Carol -- learn to cook.

Muir Glen ketchup used to be sweetener free -- and tasted marvelous -- but then they got bought out by Kraft (I think) and the sweetener went back in. It is, however, still corn free and available in the US.
