Yuca, a starchy tropical root vegetable, takes the place of potatoes in this fresh variation on mashed potatoes, which is also studded with sautéed corn and green peas. Look for yuca, sometimes called “cassava,” in the produce section of your local grocery store. You can often find it in Latin and Asian markets.

Note: Raw yuca contains toxins which are concentrated in the skin, so always peel and cook the root before eating it.
