Eat naan for breakfast, drink yogurt or white cheese (at first glance, I thought it was tofu). But the most is black tea, three meals a day is almost the same. Iran is the seventh largest tea producer in the world. Drinking black tea requires formula sugar, and the cube sugar is not directly flavored with tea, but contained in the mouth. Every bite is sweet, because this kind of sugar cube has low sweetness and is not easy to melt.
