Reuters correspondent Pascal Fletcher samples fresh camel milk by the roadside in Mauritania's capital Nouakchott, March 24, 2007. Fresh from the udder, camel milk is topped by a thick white froth. It tastes different to cow milk, less fatty and sometimes a bit saltier, and its chemical composition is very different. Picture taken March 24, 2007.
