As spirituality fills the air, people are automatically drawn to the iftar table at sunset when it is time to break Fast. That is in Ramadhan the month of Muslim fasting.
You do not have to be a practicing Muslim to want to join in. Fortunately, hospitality is second-nature to Iranians and people of the region. So it would not be hard to get a taste of the puddings and savories served, and a sense of the appreciation that comes after a whole day of abstinence from food or drink. That is abstinence from dawn to dusk, that goes on for the whole of the 9th month of the Islamic lunar calendar!
