German Potato Salad

This is like my grandfather used to make. It's a recipe handed down from his German immigrant father

6 medium boiled potatoes 2 tablespoons flour
2-3 stalks celery, chopped ¼ cup vinegar
1 green bell pepper, chopped ¼ cup water
2 hard-boiled eggs, chopped ¼ cup sugar
4 slices bacon salt and pepper to taste
1 medium onion, chopped
bacon drippings

Peel and slice potatoes. Place in a large bowl. Add celery, green pepper and eggs and stir gently. Fry bacon until crisp: partially drain skillet (leave some of the bacon drippings in the skillet. Saute onion in the bacon drippings. Crumble bacon and stir into the onion. Add flour, vinegar, water, sugar, salt and pepper. Mix well. Cook until the mixture has thickened, stirring constantly (mixture scorches easily). Add more water if the mixture is too thick. It should be the consistency of thick syrup. Pour over the salad and stir gently.
