Ham! Sweet potatoes! What a fantastic combo.
Here's what you do for ham-y sweet potatoes. Take half of a pre-cooked ham. Score the outside. Slice the sweet potatoes. Line a baking dish with sweet potatoes. Place the cut-side of the ham on the sweet potatoes. If you wish, apply a glaze to the ham (I mix grainy mustard and brown sugar). Bake at 350*F until the internal temperature of the ham is 140*F.
By then, the potatoes are also done...and delicious....and taste smoky and salty and, well, kind of like ham.
