I cannot tell you how much I love mushrooms and the famous mushroom soup. For me, this is a perfect soup for summer which I enjoy warm or cold for lunch or dinner. There are a lot of recipes on internet and I should agree that you can never go wrong with any of them. You can use fresh or canned mushrooms; whatever you like. The type of mushrooms used is also important when it comes to taste, so choose your favourite ones :).
I should mention that this recipe is the best and easiest I have ever tried. I was impressed myself by the taste and flavor. It feels so fresh and the mushroom taste is extremely authentic. Try it out and let me know how much you love it. Enjoy it!
