It’s quite bitter-tasting on its own, so people frequently add sugar to it to make it more palatable.
It is usually served in two small glasses with a small metal teapot containing a sprig of mint and some loose-leaf teas. According to Wikipedia, it can either be green tea leaves or (!!!) tobacco, which would explain the incredibly bitter taste once you reach the dregs of the teapot.
Also had an idea for a cupcake (which i discovered last night after eating a very rich chocolate mousse and washing it down with mint tea): dark chocolate cupcakes with Moroccan mint tea frosting.
