- Preheat the oven to 400˚F. Line a shallow baking pan with parchment paper. With a sharp knife, make a series of widthwise slices into the top of each yam, spacing them about 1/8” to 1/4” apart, and slicing about three quarters the way through. Set the yams, cut side up, in the baking pan. Bake, uncovered, 30 minutes.
- When the yams have baked 30 minutes, remove from the oven. Run the back of a fork across the tops of the yams, and using light pressure, fan the slices, slightly separate them from one another.
- Combine the butter, oil, sage, garlic, syrup and juice in a small bowl. Brush half this mixture on top of the yams and in between the slices. Season the yams with salt and pepper. Bake the yams 15 minutes more.
- Brush the top of the yams with the remaining butter mixture, and then bake 15 minutes more, or until tender. Set yams on a serving platter, brush with the liquid left in the pan, and then serve.
Options: Instead of fresh sage, use 2 tsp. of dried sage leaves in this recipe. Instead of maple syrup, use an equal amount of honey.
