Cauliflower Soup

I just made the soup. I did not make the mustard croutons. This soup was good, but the next time I make it, I will make a few adjustments. I felt that the potato overwhelmed the cauliflower flavor. Next time, I would increase the cauliflower to 24 oz (roughly one whole head). The recipe called for a homemade Dijon mustard, but I just used what I had on hand and felt that the mustard flavor was not prominent enough. Next time, I would increase the mustard to 2 tablespoons.
