Creamier than a classic potato salad, and chunkier and zestier than regular mashed potatoes, this hybrid dish can be served warm or at room temperature, when its texture is at its softest and best. (Never serve this cold; no one likes cold mashed potatoes.) The key to getting the right texture is to cook the potatoes a little more than you would for potato salad, but not so much that they completely fall apart. You are looking for chunks of potatoes coated in a fluffy layer of highly seasoned mashed potatoes. Potato salads tend to absorb their seasonings as they sit, so for the most flavorful dish, be prepared to add more salt, lemon juice and olive oil to taste just before serving.
