3 lbs. (10 to 12 medium potatoes)
1 c. chopped onions
1/2 tsp. celery seed
2 tsp. salt
1/8 tsp. pepper
6 slices bacon, diced
1/2 c. cider vinegar
2 tbsp. sugar
3 tbsp. water
1 egg, room temperature and beaten
2 tbsp. minced parsley

Cook potatoes in boiling, salted water until tender (in packets). Cool slightly; peel. Slice thin into large casserole bowl. Add onions which have been sauteed in bacon drippings. Mix vinegar, sugar water, and bacon drippings; heat to simmering. Add very slowly to beaten egg. I do this in blender at low. Pour over potatoes. Add bacon and parsley. Mix lightly. Serve warm. Keep warm at 200 degrees in oven, covered. Makes 8 servings or 7 cups.
