Can I blend hot soup in a ninja? I want to make broccoli cheddar soup tonight and it says to blend the stuff after you add the broccoli. I have a blender but it sucks and would rather use my ninja. Can I put hot liquids in this? How do I deal with venting the steam?
According to the manual of the Ninja Professional Blender:


  CAUTION: Do not process food or liquid that is hotter than 180°F/82°C. Allow very hot ingredients to cool before processing.
