Boil the sweet potatoes with peelings on (this leaves nutrition to them) 25 minutes. Cool to touch, peel potatoes, and place in a mixing bowl. Combine orange juice concentrate, water, honey, and butter mix well. Add 1/3 of this orange juice mixture and sugar to potatoes. Beat potatoes mixture at medium until fluffy and smooth.
Spoon potato mixture to a 2 1/2 quart casserole, then brush remaining orange juice mixture over potatoes.
Bake uncovered about 20 minutes at 350°F. After 20 minutes, place the 22 Jet-Puffed Marshmallows (cut marshmallows in halves) over the sweet potato casserole. Bake another 20 minutes or until marshmallows slightly brown or puffed.
