[Update: Benne Murukku was featured on the kitchn on Oct 14 2011]
Back in the olden days, making Murukku traditionally was quite an elaborate affair. Short grain rice would be washed and allowed to dry spread out on a clean white cloth. When dried, it would then be stone ground in small handful batches to a fine powdery flour and the same repeated for roasted Urad dal/split Black gram as well. And the whole process would easily take couple of days before the actual making begins!
I know it verbatim because that was exactly how it was made in my grand dad’s house every year for the festival of Gokulashtami up until a decade ago. No wonder those murukkus were heavenly!
