Prep: Core and chop pears.
Steam: Fill a medium saucepan with 2 inches of water, and bring to a boil over medium heat. Place the pears in a steamer basket over the boiling water, cover and cook for 10 minutes or until tender. Let cool slightly. Reserve steamer water.
Soak: Meanwhile, in a small bowl, add the prunes to the hot water, and let sit for 10 minutes. Drain.
Add: Place the pears, prunes and cloves into blender or food processor.
Puree: Start on low speed and work the blender up to high speed for 1-2 minutes or until completely smooth, adding water from the leftover steamer water in 1/4 cup increments, if needed.
Eat: Serve to baby, or freeze for later.
