Somebody asked, 'What is manioc?'
Manioc is otherwise known as Cassava. It's a small spindly shrub with a tough woody root full of starch.
The root is used in cooking. It can be boiled and is rather plain, or it can be mixed with coconut milk and made into lap-lap which is really yummy.
It has to be prepared appropriately to get rid of toxins (or a bitter taste), so don't try it at home.
I have heard that it is the same as arrowroot and tapioca but I am not sure about this.
