I love spinach cream and this recipe has leek in it. From Ricardo. ETA : I made it on August 27, 2011. I didn't use celery salt. I used a bag of near 170 g of spinach. After I pureed it, I tasted it and liked it that way without anything else. My son that is very picky liked this soup. I was kind of surprised. After he tasted it, he wanted a bowl.
