When I spent time in Morocco a couple of years ago, I found harira on nearly every menu. Traditionally, it is the food that breaks the month-long, daylight fasting of Ramadan, but I was told by more than one old geezer that it was also referred to as "Smoker's Soup" because it helped purify the lungs. From what I saw, these men most likely ate spoonfuls of the stuff between long drags on their Marlboros.
Owing to the fact that I was not only riding, eating, and wearing camels, but smoking a hell of a lot of them, too, I decided to join them in their health regimen. My lungs didn't necessarily feel any better, but my stomach did. And maybe my soul, too.
Two years later, as I struggle to leave the Camels back in the Sahara where they belong, I have returned to harira in my latest and most successful attempt at purification. Nowhere on the internet could I find any mention of this being a smoker's soup. Of course, the old men who imparted this wisdom looked as though they'd never heard of a gmail account. God bless them and I pray that they never do.
It comforts me to know that you can't find everything by Goggle search.
