In my neighbourhood, the majority of people still eat by hands.
I tried once near Reo to have rice sauce with my fingers, and the experience was not unpleasant.
Of course, the psychological burden of childhood’s first commandment: do not eat by your hands converted this incident in a cultural shock.
Eating by hands could look as an uneducated behaviour, but is not. You have to wash carefully your hands before and after the meal and there are some more rules of etiquette, especially if you are sharing the bowl with others (that is the natural African complement to this way of eating).
If you enjoyed the chopsticks Chinese way, now try your fingers, you’ll not regret.
