Figs are abundant this time of year--your last chance to taste them until spring.
Heat broiler. Place figs, cut side up, on a cookie sheet. Sprinkle the sugar over the figs and dot with butter. Place figs under the broiler as close to the flame as possible and cook until they begin to brown around the edges, about 2 minutes. Place 2 fig halves on each of 4 plates, along with a scoop of ice cream. Drizzle 1/2 tablespoon honey over each scoop of ice cream and sprinkle figs with pepper, if desired. Garnish with mint sprigs.
