Summer Salads Part II

Horseradish Potato Salad

3 pounds small (2-inch) potatoes, your choice of variety (I found a rainbow-colored ones at my local farmer's market)
1/4 cup red onion, chopped
1 tablespoon white-wine vinegar
1 cup sour cream (or 1/2 cup sour cream, 1/2 cup yogurt)
2 tablespoons fresh dill, finely chopped
1/4 cup chopped fresh chives (frustratingly, couldn’t find these)
1 tablespoon Dijon mustard
3 tablespoons prepared horseradish
1 teaspoon salt
1/2 teaspoon black pepper

Boil the potatoes until fork tender, cool them to room temperature and quarter them. In a large bowl, mix the remaining ingredients and fold over the potatoes. Adjust seasoning to taste — you might add another tablespoon of vinegar if you feel it needs more ‘zing’.
