The orange things are sliced sweet potatoes mixed with butter. The white stuff is obviously sugar. The brown power is probably a pre-mix of brown sugar, cinnamon, and nutmeg. The dark brown liquid is probably a pre-mix of water, molasses, and vanilla. Into the oven it goes for an hour or two until the sweet potatoes release their water, the sugar melts and reduces to become a thick syrup, and the sweet potatoes absorb the syrup.
It's a very common side dish made for Thanksgiving and around that time of year.
