Here is an easy chilled soup to make in the Spring when the weather is beginning to warm up. Make it early in the day or even a day ahead so the flavors blend and develop. This is a beautiful soup and it can be served as an appetizer at a fancy dinner party. Leeks have a sharp, strong taste when it is raw, and a soft and sweet taste when cooked. Here the leek is the main ingredient and taste bedst in the late Spring and early summer when it is fresh. The fresher a vegetable, the higher the nutrition.
