In a large saucepan or Dutch oven, cook the salt pork or bacon until crisp. Add onions and cook until they soften somewhat, about 4 or 5 minutes. Sprinkle flour over the onions, add bay leaves and thyme; increase the heat to high. Pour in wine and stir to loosen brown bits from the bottom of the pan. Cook for about 2 minutes, or until wine has evaporated.

Add potatoes, broth, and pepper. Cover and bring to a boil. Reduce heat to medium low and simmer until potatoes are tender, about 45 to 60 minutes. Sprinkle with paprika, if desired. Taste and adjust seasonings. Remove bay leaves before serving.
