German Potato Salad

Boil the potatoes until tender, then cool just enough to handle, peel, and slice them.

Place the warm potato slices in a large bowl and add the finely chopped onions.

Fry the diced bacon until crisp, then lift it from the grease and scatter it over the potatoes.

Brown the flour lightly in the bacon grease to make a roux.

Whisk in the vinegar, sugar, salt, pepper, and water, then boil until the dressing thickens.

Pour the hot dressing over the potatoes and bacon and stir gently but thoroughly.

Serve warm, or hold covered so the flavors continue to soak into the potatoes.
