Immersion Blender

I have had a simple Rival Immersion Blender for years.  I had never really used it other than to froth milk for coffee or hot chocolate.  Recently, I have discovered that I like to use it.  I used it again this evening as I made homemade chicken noodle soup for our supper.  I save the leaves and scraps from celery in a bag in the freezer.  I wanted the celery flavor along with onion flavor without necessarily having the pieces of either one in the soup.  I cooked some celery stalks and a half of a yellow onion in butter.  I added about two cups of the stock broth.  Once it was all nearly boiling, I removed the pot from the stove and used the immersion blender to blend it all together.  I had read once that cooking vegetables and then using the immersion blender in them makes a "cream" soup without having to add cream.  I have found this to be true. The liquid that I made out of the celery, onion, butter, and stock was creamy.  I tasted it and found that it was full of flavor.  I added the rest of my chicken stock to it along with the shredded chicken.  I will add more flavors once it has time to cook together.
