Preheat the oven to 350ºF. Cut the pears in half lengthwise. Scoop out the seeds and pith in the center of the pears and discard. Place the pears, cut side up, in a baking dish.

In a bowl, mix together the nuts, sugar, cinnamon, cloves, and salt. Spoon the nut mixture into the cavities of the pears, mounding it up. In a small pot over low heat, melt together the butter, honey, and lemon juice, stirring often. Brush the mixture over the pears.

Bake for 20-25 minutes or until the pears are tender. Serve warm with ice cream.
