2 1/2 lb. potatoes, preferably new
1/3 c. cider vinegar
2 tbsp. sugar
1/4 c. corn oil
1 tsp. salt
1 tsp. pepper
4 hard cooked eggs, chopped
1/3 c. finely chopped onion
2 tbsp. minced parsley
1/2 c. real mayonnaise

Cook washed unpared potatoes in boiling salted water just until tender. Meanwhile in a small mixing bowl, with a fork, beat together the vinegar, corn oil, sugar, salt and pepper; set aside but beat together again just before using.

As soon as potatoes are tender, drain and remove skins; slice into a large bowl; while potatoes are still hot, add egg, onion and parsley and toss lightly; immediately pour over the oil mixture but do not toss.

Let marinate at room temperature for 1 hour. Add mayonnaise and toss lightly. Serve at room temperature or chilled. Makes 6 (1 cup) or 8 (3/4 cup) servings.
