Austrian-style Warm Potato Salad

Ingredients

 * 1 pound small fingerling potatoes, washed
 * 2 sprigs fresh thyme
 * 2 1/2 tablespoons kosher salt
 * 1 small yellow onion, finely chopped
 * 3 tablespoons sugar
 * 1/2 teaspoon freshly ground black pepper
 * 1 cup white wine vinegar
 * 1/4 cup canola, safflower, or peanut oil
 * 1/2 cup chicken broth or vegetable broth
 * 1 tablespoon finely chopped fresh parsley leaves or chives

Directions
In a large saucepan, combine the potatoes, thyme sprigs, and 2 tablespoons of the salt. Add enough cold water to cover completely. Bring to a boil over high heat. Reduce the heat to maintain a simmer and cook until the potatoes are just tender enough to be pierced easily with a skewer or the tip of a sharp knife, about 10
