Years ago, I visited a friend on Christmas Eve night since I was not returning to my family gathering in Virginia over the holidays. My friend served “Chicken and Sausage Gumbo.” How interesting, I mused, to serve a simple soup on this special occasion. Since that dinner, I have eaten gumbo at other Christmas Eve night celebrations. And I have learned that gumbo holds a very reverend traditional place in Cajun and Creole families on Christmas Eve. I am attempting to reproduce my friend’s gumbo — a deep colored, flavorful soup with chicken and sausage. It was, by far, one of the best gumbos that I have ever eaten.
