This is one of the many things I like about Rwanda - African Tea. It seems to be made of tea, hot milk and ginger. At some places, such as this coffee shop in the city centre in Kigali, at a shopping mall overlooking the valley, you can clearly see and taste the tea. There is also un-mistakenly ginger, but it is not overwhelming.
At other places, however, there seems to be hardly any tea in the "African Tea". It looks more like just hot milk with ginger in it. Even then, it is quite enjoyable. According to my Rwandan friends, it is quite popular all over East Africa.
