6 large Irish potatoes
1/2 cup sour cream
1/2 cup plain yogurt
1/4 cup fresh chives, finely chopped
1 tsp salt
black pepper to taste

Scrub and boil potatoes in jackets until fork-tender. Drain, peel and cut into 1/2 inch cubes. In a salad bowl, combine the potatoes, sour cream, yogurt, and chives; toss gently to coat. Add salt, and pepper to taste; refrigerate until chilled.
