The Campbell's soup that comes out in one clump...I think that those are all the condensed varieties. They are thicker and come out that way because you are supposed to be adding milk, unlike the other brands, which are ready-to-serve. I like to use the condensed ones for cooking, as they are more flavorful, and I usually end up adding broth or milk, so it thins it out.
For cream of tomato soup, I like the Seeds of Change (in the organic section). I'll add a little leftover rice to it, sprinkle on a bit of grated parmasean. Mmmmm!
