For each fig, cut a cross over the stem end, just deep enough to gently squeeze the fig open. Place on a baking sheet and bake in the oven for 5 to 10 minutes. Meanwhile, combine the honey and mascarpone in a bowl. Coarsely chop the pistachio nuts, and then add them to the bowl. Remove figs from the oven. Place on a serving plate and top with mascarpone mixture. Garnish with cinnamon and grated dark chocolate.
