Directions
Saute onion, celery, white slices of scallion and garlic until translucent in 3 tablespoons of butter and set aside.
Make a roux with 4 tablespoons of butter and 1 tablespoon of bacon fat and flour. Gradually add milk, constantly stirring, and bring it to a boil. Stir for 5 minutes while in a rolling boil. Lower the temperature, add Old Bay seasoning, potato soup and bacon to make a stew.
Use remaining butter to heat oysters and their juice (oyster liquor). Add parsley and green parts of the scallion. Cook until oysters begin to curl. Add oysters into the stew. Serve with oyster crackers, Old Bay seasoning and sherry.
