Wash and cut the pears into 3 or 4 pieces, removing the cores if necessary, then place them on a hot griddle. Meanwhile, combine 4 tablespoons of honey with a handful of chopped walnuts in a small saucepan. Sprinkle the pears with brown sugar and place them directly on the hot griddle, leaving the heat on until they are golden brown. Just before removing the pears, melt the honey and walnuts. Serve the pears with a scoop of ice cream, preferably vanilla. Drizzle generously with honey, then add fresh mint leaves to give your dish a stunning flavour.
