Step 2
In a large heavy-bottomed stock pot over medium-high heat, combine 1/4 cup butter and flour. Cook, stirring constantly, until the roux becomes chocolate brown. Stir in the vegetable mixture, and stew meat. Cook, stirring, until vegetables are tender, and meat is evenly brown. Stir in water, tomatoes, and sugar. Season with parsley, thyme, bay leaves, salt, cayenne pepper, and black pepper. Bring to a boil, reduce heat, and simmer for 2 1/2 hours, stirring occasionally.
