2 pounds sweet potatoes, peeled and cut into ½-inch pieces
¾ cup brown sugar
½ cup freshly-squeezed orange juice
4 ounces unsalted butter, cut into pieces
1 tsp freshly-ground cinnamon
Cover potatoes in a large pot with cold water by at least an inch.
Cover and bring to a boil over high heat. Reduce heat to a simmer and cook until potatoes are tender (about 15–20 minutes).
15–20 minutes
Drain potatoes into a colander. Remove water from pot and add potatoes and remaining ingredients. Mash potatoes with either an immersion blender or potato masher.
If you used a potato masher, combine ingredients thoroughly. If you did not, then you can skip this step.
Serve immediately.
