Remove the core from each pear and discard. Roughly chop the pears into pieces. You do not need to peel the pears.
Place the pear pieces into a blender and process until smooth, scraping down the sides as necessary.
Transfer to a small bowl and serve immediately, or store until ready to use. Store in an airtight container in the refrigerator for 2 to 3 days or in the freezer for 4 to 6 months. The exposed top layer of the pear puree might start to brown in the refrigerator; scrape away and discard.
