Tunisian Potato Salad With Cumin - cooking recipe

Ingredients

1 1/2 lbs potatoes (I tested Yukons)
1/4 teaspoon harissa (to taste)
1 teaspoon ground cumin (if you have time, gently dry roast the cumin powder in a cast iron skillet)
1 large lemon, juice of
2 tablespoons extra virgin olive oil (Shulman uses much less but I love my olive oil!)
1/4 cup plain yogurt, to desired consistency
2 tablespoons fresh cilantro (FRESH!) or 2 tablespoons fresh flat leaf parsley, minced (FRESH!)

Preparation

Steam or boil the potatoes until tender-about 15-20 minutes. I *very* slightly undercook the potatoes for best results. *After the potatoes have cooked, refresh under cold water, drain and cut into cubes. *Note: when I made this potato salad recipe I drained the potatoes, placed them in a bowl to cool until just warm and proceeded with the recipe. After the potato salad had cooled in the refrigerator then the fresh cilantro was stirred in just before serving. I wanted to avoid \"cooking\" the fresh herbs.
Combine the remaining ingredients except for the herb(s) in a large bowl and mix well. Add the potatoes to the bowl and toss with the dressing. Can serve warm; or chill and serve (depends on time of year).
Stir in the herbs just before serving.
