Red Gold has always been my favorite canned tomato. Never having done a side-by-side test, my opinion is anecdotal, but the tomatoes have a certain ... je ne sais quoi. They seem more tomato-y and more flavorful, or maybe they're a different variety than other canned brands. Other people agree. (Warning: It's a Facebook link.)
The ketchup is less sweet than Heinz, and a little more vinegary, and seems to have a richer and more concentrated tomato flavor. I know Bites readers get around — has Red Gold ketchup been turning up in your restaurant travels, and do you think it can challenge Heinz's world domination?
