In a very large pot, cook meat until almost browned. Add celery and onion. Stir in flour slowly. Add remainder of the ingredients and simmer for at least 30 minutes. If the mixture seems dry, or needs a little punch of flavor, I add a little bit of bottled bbq sauce.
Adjust seasonings to taste.
When I watched the church ladies make this, they used a large canning pot to make this recipe.
