Carefully transfer your soup to a blender. If you've never blended a hot liquid before, you're in for a treat (i.e. you may want to toss it in the fridge for a bit to not risk disaster). Make sure the lid is on nice and tight. You probably wanna throw a dish towel over the top for good measure. Make sure your blender is on it's lowest setting. Pulse a couple of times to test the waters. When you think she can take it, start giving her more power. If you can get up to 30 seconds on high power, your soup is probably pretty smooth. Pour it back into the pot.
