Spicy Potato salad with Sesame Seeds

This potato achaar is a popular, addictive, and refreshing potato salad. Only rarely have I come across a traditional Nepali meal that does not include potato achaar. For this recipe, use any variety of waxy potato that keeps its shape when boiled. Baking potatoes are not recommended because they produce a dry, starchy achaar. Although this is called an achaar dish (pickled), it is more like a side vegetable dish. It is served at room temperature.
