Ingredients
Scale
- 4 pounds (1.8 kg) orange sweet potatoes (garnet or jewel), about 5 medium, peeled and sliced into 1/2 inch rounds
- 1 tablespoon unsalted butter, for the dish
- 1/2 cup (115 g) unsalted butter
- 3/4 cup (150 g) packed dark brown sugar
- 1/4 cup (50 g) granulated sugar
- 1/3 cup (80 ml) water
- 1 teaspoon ground cinnamon
- 1/2 teaspoon ground ginger
- 1/4 teaspoon ground nutmeg
- 1/8 teaspoon ground cloves
- 3/4 teaspoon fine salt
- 2 teaspoons vanilla extract
- 1 teaspoon finely grated orange zest
- 1 1/2 cups (75 g) mini marshmallows (optional)
- 1/2 cup (55 g) pecan halves, toasted (optional)
Instructions
- Heat the oven to 375°F (190°C). Butter a 9×13 inch baking dish. Peel the sweet potatoes and slice them into rounds a half inch thick, keeping the slices as even as you can so they finish together.
- Arrange the rounds in the dish in slightly overlapping rows, like fallen dominoes. A single crowded layer with light overlap is right; the slices settle as they soften.
- In a medium saucepan over medium heat, melt the butter. Add both sugars, the water, cinnamon, ginger, nutmeg, cloves and salt. Stir until the sugar dissolves, then simmer gently for 2 minutes, until glossy.
- Take the pan off the heat and stir in the vanilla and orange zest. Pour the hot syrup evenly over the potato rounds, then turn a few slices with a spoon so every face gets a first coating.
- Cover the dish tightly with foil and bake for 35 minutes. The slices should be softening and the syrup bubbling at the edges.
- Remove the foil. Spoon the pan syrup over the slices, turning any pale pieces face down. Bake uncovered for 15 minutes more, until a knife slides into the thickest slice with no resistance and the edges show light caramel color.
- Tilt the dish carefully and pour the pan syrup back into the saucepan. Simmer over medium heat for 3 to 4 minutes, until it thickens enough to coat the back of a spoon and leaves a clear trail when you draw a finger through it.
- Pour the reduced glaze back over the yams and let the dish rest for 10 minutes. The glaze will set to a shine as it cools slightly. Serve warm, with the toasted pecans scattered over if you like. For the marshmallow version, scatter the mini marshmallows over the glazed dish and broil 1 to 2 minutes until golden in spots, then serve immediately.
