Back in northern Nigeria we established that the market is one of the best places to find Osamas. Having trawled the more touristy sections of Cairo's main market earlier this week, we aimed for somewhere a little grittier today and traversed the glistening model pyramids and scarab pendants to reach chunky silver markets and finally, textiles.

We found loads of Osamas, but the shouting crowds, grime and heat were intense. People went absolutely nuts as the search gathered momentum. One Osama took us to another Osama who took us to another. This is exactly how we dreamed it would be! The only drawback was that the heckling was massive and it was hard to record. Since I don't speak Arabic, it was hard at times to tell whether the crowd were angry or just really, really excited - it was the latter.

Several Osamas had left their stalls to pray. The call to prayer over Khan El Khalili from the magnificent entrance mosque was haunting and beautiful as the green minaret lights switched on at dusk.

My personal favourite Osama from today was the lovestruck Koshary seller who wouldn't reveal the object of his affections by name but was clearly utterly besotted by her. He could think of little else as he fried onions and simmered lentils all day dreamily.
