Oca is a colorful and flavorful tuber from the Andes, unrelated to yams or potatoes. These small, waxy tubers come in a variety of vibrant colors like pink, red, and yellow. They have a unique, slightly tangy and lemony flavor with a crisp texture when raw. When cooked, the tanginess mellows, and they become soft and starchy, with a nutty sweetness. A versatile and exotic alternative to potatoes, perfect for roasting, boiling, or slicing into salads.
