Use whatever recipe your family uses for buttermilk cornbread.. no sugar or very little.. add 3/4-1 cup mashed cooked PLAIN yams.. blend until well mixed.
I use salted butter for my fat in my bread as well as to grease the pan.
Candy yams as you normally would and let them cool slightly.. once your cornbread batter is in the pan use a large spoon and scoop your candied yams and any candied sauce in the middle.
Bake 400 until cooked in the center.
When it comes out pour 1/2 stick of warm melted salted butter mixed with 1 +/- tablespoon honey over the top.
