How to Blender Puree Hot Soup

As previously noted, I prefer using an immersion blender to puree my soups. However, I realize that the immersion blender isn’t  a common kitchen tool, so I wanted to outline the correct (safe) procedure for pureeing a hot soup in a regular blender:

1. Hot liquids will expand when blended, so be careful not to fill the jar of the blender more than halfway (puree in batches if necessary).
2. To prevent the liquid from spattering, allow the heat to escape: Remove the cap from the hole in the lid, and cover the lid with a dishtowel when blending.
3. Repeat if necessary. Return soup to a clean saucepan to warm (for warm soups, obviously).*

    I had an AWFUL experience with Kitchenaid! The rubber drive got soft, melted nad wont firm up meaning the whole blender is now useless.. the rubber drive gear can not be replaced on mine… (the rubber drive is attached to motor in base and integrates with the metal wheel on bottom of the blender jar).. If you do puree hot stuff… Id say use one with as LITTLE rubber as possible anywhee… Kitchenaid is NOT a good choice for a hot-puree blender… Oster is..

    My Kitchenaid did the exact same thing this past weekend. I heard this weird noise and stopped the blender and when I removed the picther the rubber just fell off. (I had used it several times in the past to puree hot soup). I guess it finally gave up. Finished with my immersion blender. Now we are looking at purchasing the Oster BCBG08.
