Add the salt, pepper, and cream, and blend well. Remove from the heat and ladle into hot soup plates. Top with Vidalia onion rings and Creme Fraiche.
Creme Fraiche – In a saucepan combine the cream and sour cream. Mix well and heat over low heat until warm. Put into a covered jar and let sit at room temperature for 6 to 8 hours. Refrigerate overnight before using. Keeps 2 to 3 weeks.
