Slow Cooker Black Forest Sausage And Sauerkraut

1 lb bacon, diced and fried crisp
1 medium yellow onion, diced
1 Tbsp flour
2 lbs sauerkraut, drained
2 lbs bratwurst or kielbasa, cut into 2 inch chunks
1 cup apple juice
1/4 cup packed brown sugar
2 large tart apples, cored and diced
1 tsp caraway seeds

Fry the bacon in a large skillet until crisp, then remove to a paper towel, keeping the bacon fat in skillet.
In the same skillet, add the onion and cook until slightly softened.
Sprinkle in the flour and whisk, cooking just until flour turns yellow and thickens into a roux.
Add the sauerkraut to the skillet, stir to get up all the browned bits in skillet, then dump mixture into crockpot.
Add the remaining ingredients to crockpot, stir to combine.
Cover and cook on LOW for 4 to 6 hours, until sausage is cooked through.
Serves 6 to 8.
