Sweet Potatoes vs Potatoes

[unspeakablehorror]

One of the major differences between sweet potatoes and potatoes is that you can eat the whole sweet potato plant.  Of course potato plants have quite poisonous leaves and stems like many other members of the nightshade family.  But sweet potatoes are in the morning glory family, and happen to be completely edible.  I recently enjoyed a tofu stir fry with some larger sweet potato sprouts (one had grown to be about a foot long!) and today I am cooking the actual root portion as sweet potato fries.
