Beer from Macaroni

Habib and I were working our way through a 12 pack of Corona Extra tonight. He mentioned that they can only buy non-alcoholic beer in Iran, but that folks who want the leaded version make it themselves. Towards this end and to remain inconspicuous they grind up macaroni as the fermentable base and swipe barley from the horse's feedbag. Now that's true American pioneer spirit!!
