1 teaspoon prepared horseradish
2 garlic cloves, minced
1/2 teaspoon celery seed
1/2 teaspoon salt
1/4 teaspoon pepper
Dash onion salt

Place potatoes in a saucepan and cover with water; bring to a boil. Cook for 20-30 minutes or until tender; drain and cool slightly. Slice potatoes into a large bowl. In a small bowl, combine the mayonnaise, sour cream, yogurt, onions, pickles, mustard, horseradish, garlic and seasonings. Pour over potatoes and toss to coat. Gently stir in eggs.
