Hungarian mushroom soup from the Moosewood cookbook. I could eat a few gallons of it. I also agree with #'s opinion on Campbell's Cream of Mushroom.

I never liked tomato soup because the only thing I've experienced has been Campbell's. I think this is what Bat Goddess makes, and I plan on trying it this summer: Fresh Heirloom Tomato Soup from The Splendid Table

I'm now hungry.
