  • You can find recipes for plain yogurt on the Internet, and they generally call for just two ingredients, milk and a yogurt starter. (Sometimes they add a third, powdered milk, which is supposed to make the yogurt thicker.) Most sweeteners, flavorings and added ingredients such as berries usually are added just before serving.
