Yam is basically a sweet potato, but itís not called that, which is super confusing. Itís an orange, potatoĖlike root vegetable. For a loose analogy, yam is to sweet potato as plantain is to banana.
Yam tastes good, because it has a sort of naturally sweet flavor. Itís not as good as sweet potato, because itís not quite as orange.
Yam became an official snack on June 19th 2012.
