Cauliflower Milk Soup
Potato gives a smooth cauliflower soup body, while milk softens its flavor. It is a gentle lunch with no need for a separate flour-based sauce. Cook the vegetables until they crush easily before blending, then add the milk and warm gently. A vigorous boil at that stage is more likely to make a mess than improve the soup.
