"The flavor of this soup can vary depending on the degree of ripeness of the brie cheese. If you put your brie cheese out at room temperature for 3 to 9 hours, this will intensify the brie flavor in your soup."
1Melt butter in sauce pan over low heat. Add flour and mix well, cooking until it just starts to turn golden.
2Add stock and whip vigorously, bring to boil and reduce to simmer. Skim the butter and flour and other impurities that rise to the top and continue to simmer until the veloute is reduced to 2/3 its original quantity and the sauce is the consistency of heavy cream.
3Strain through fine sieve.
4Return veloute to sauce pan over low heat and add brie cheese, cook slowly, stirring occasionally, until the cheese has melted. Add wine and vegetables and simmer lightly until the vegetables are al dente. Heat heavy cream over low heat and add to soup. Season soup to taste with salt and pepper. Garnish with fresh chives or scallion.
