Yam vs Sweet Potato Tip

Yesterday while cooking for a client my recipe called for Sweet Potato-which by the way in my opinion is better tasting and is much better for you! Anyway, as I was peeling what I thought was a sweet potato to my surprise was a Yam!

Yikes I was disappointed-

I told my client later in the day that her meal of Vegetarian Enchiladas had yams in it instead of sweet potatoes and her response was "Oh that has happened to me before so now I always make a little scratch mark to be sure the flesh is that of a sweet potato the orangey color vs the white of the yam!

So I may have to try that going forward
