This casserole was designed to please those folks for whom Thanksgiving wouldn't be complete without some sweet potatoes, but to also please those who don't care for a large hunk of orange doused with a sticky, sweet sauce. Sure, in essence this recipe is like lumpy mashed potatoes. But those mashed bits will actually hold on to that tasty sweet sauce rather than letting it running all over your plate. And the unmashed bits have enough texture left that they'll remind those who crave a big hunk-o-yam of what they like best. Everyone's happy — except those who just don't like sweet potatoes, period.
