In a large skillet over medium heat, cook the bacon until crispy. Remove the bacon to a plate lined with paper towels and set aside to cool. Once cool, crumble the bacon.

in the same skillet, sauté the onions for 3 minutes. Whisk in the flour, sugar, celery seeds, 1/4 teaspoon salt, and a dash of pepper. Stir until it bubbles and then add the water and vinegar. Stir over medium-high heat until the mixture bubbles. Stir in the bratwurst and potatoes. Heat again until bubbly. Serve with scrambled eggs or eat alone.
