Since Thanksgiving is virtually around the corner, and now is the time for orange vegetables to assert their place, I felt it was high time to re-introduce you to my favorite sweet potato gratin recipe. This is a smoky, rich gratin, with a streak of caramelized onions and garlic sandwiched between layers of sweet potatoes baked in cream. I hate to sound like I am bragging, but just to put it in perspective, every time I have served this, grownups have literally licked their plates and groaned aloud.
What I can say? It's the power of sweet potatoes in cream.
