Fufu is one of the favorite meals of Togolese. It can be made from manioc, yam or even taro. Basically you boil whatever carb you've got and then you beat it with a big stick and add water. When I first learned of fufu in Togo I optomistally hoped it would be like mashed potatoes. It's not.
But, given enough time, I've learned to like it. The other night my host family was cookin' some up so I crashed the party. In fairness I decided to help out by pounding the fufu. I can't say that actually helped them at all, but it had comidic value at least.
