Yam is kind of food found in Far Harad. It is very similar to potatoes. Yams were added to the Mod in Public Beta 31.
Yams grow in patches in the savannah. They can also be found in the inventory of Morwaith dwellings.
As with potatoes and other seedless crops, yams can be grown by planting one on tilled soil. The growth process can be shortened by using bone meal on the growing yam.
By baking yams in an oven, one obtains a roasted yam, that will restore 6 ().
It is highly recommended to roast yams before eating, as they will induce hunger when eaten raw; even though it restores 1 (), you might end up hungrier than you were before.
They make a good source of food for the Morwaith and everyone venturing into the far south of Middle-earth.
