Toast the baguette slices for 12 minutes at 350°F or until stiff to the touch. Cool the bread. Meanwhile boil or steam the sweet potatoes until fork tender, about 5 minutes. Heat the honey, olive oil, and rosemary in the microwave for 25 seconds. Mash the sweet potatoes. Stir in the orange zest and hot honey mixture. Then stir in the salt and pepper. Cool the mashed sweet potatoes. Heat the wine, orange juice, and brown sugar over high heat until just boiling. Stir in the sliced figs. Turn off the heat. Cover the saucepan, soaking the figs for 5 minutes. Drain the figs. Prep the crostini with a smear of sweet potato and then tile one or two wine-soaked figs on top.
