Most Zambians do not feel like they have properly eaten if the meal has not involved some ingestion of nshima (en-she-ma). That is the white, grit-like stuff you see in the upper right. This is made from boiling maize meal (maize is like white, unsweet corn for those who are unfamiliar), and stirring with the strength of a "world's strongest man contestant" until the meal reaches a thick consistency.
Once the desired consistency is achieved the happy eaters take some of the nshima in their hands and proceed to make a little "nshima ball". (You can always identify rookie nshima eaters by the 2nd degree burns on their fingers....the stuff is hot!). Once the ball is made the eater then dips it into one of the other dishes (often referred to as the relish). Once ball and relish have been combined all the eater has to do is .... well, eat.... and enjoy!
To Katie's dismay the picture is quite accurate. There are, usually, no beverages (even water...so sorry Kate) served with the food. Only once the meal is over is drinking water offered. I mean come on, you don't want to fill up on water when there is only limited space in your tummy for the yummy nshima!!
