1/2 c. dark brown sugar
1/2 c. orange juice
3 tbsp. butter, plus more for pan
1 cinnamon stick
2 tbsp. bourbon (optional)
Pinch nutmeg
Pinch kosher salt
5 medium sweet potatoes (1.5 kilo)
Preheat oven to 200 c°. Butter a medium baking dish.
In a medium saucepan over medium heat, combine sugar, orange juice,
butter, cinnamon stick, bourbon if using, nutmeg, and salt. Stir to combine
and bring to a boil, then reduce to a simmer and cook until it has thickened
slightly, about 10 minutes. When reduced, remove and discard cinnamon
stick.
Meanwhile, prep potatoes: Peel potatoes and slice into 1 cm rounds, then
layer in prepared baking dish. Pour thickened syrup over potatoes and
cover dish with aluminum foil.
Bake 30 minutes, then remove foil and bake about 50 minutes to 1 hour
more, basting with sauce every 15 minutes.
Let cool slightly before serving.
