Not quite T.R.'s Celery Root Soup

Number three on my list of favorite winter soups is my own adaptation of Tal Ronnen's celery root soup. Tal Ronnen is a well known American cook, and a master at creating gorgeous meatless meals. My mother-in-law brought me his beautifully photographed cookbook called The Conscious Cook (2009) from the US a while ago, and his celery root soup (quoted by Oprah, as being 'the most popular soup she makes'), is one of the recipes I adopted but adapted to better fit my needs.
Don't let the looks of the root put you off... This soup is delicious!
