This is a great soup and the reduced balsamic adds a great contrast. Make sure you begin with a good balsamic vinegar. You do need to watch out toward the end of the reducing, because it can burn very quickly. Roasting the veggies gives a great depth to the flavor of the parsnips, pears, and onions-makes the house smell great. The instructions clearly state to use a blender to puree the roasted veggies with the liquids. Overall, this is going to be a soup that I make many times.
