Great-Grandma's Candied Yams

Step 1
Bring a large pot of water to a boil over high heat. Add yams and boil for 10 minutes. Drain and rinse twice with cold water. Soak in cold water for 15 minutes.

Step 2
While yams are soaking, preheat the oven to 275 degrees F (135 degrees C).

Step 3
Mix white sugar, brown sugar, cinnamon, and nutmeg together in a small bowl.

Step 4
Peel and cut yams into chunks and place in a large baking dish. Dot with butter and sprinkle with sugar mixture so all yams are coated. Carefully pour enough orange juice into the bottom of baking dish to measure 1/2 inch.

Step 5
Bake in the preheated oven, basting often, until yams are tender and the liquid is thick and sticky, 3 to 3 1/2 hours. Sprinkle with mini marshmallows. Turn on the oven's broiler. Broil until marshmallows are melted and toasty, about 5 minutes.
