Bartletts* are the juiciest pears when eaten raw and, consequently, lose their shape when cooked, turning to pear-sauce quite easily with the briefest exposure to heat. They are perfect for making Pear Butter or any other recipe where you want the pears to fall apart when you cook them.
Barlett pears are harvested July through October. Learn more about Bartletts with this guide to All About Barlett Pears.
*Note: Bartlett pears are also know as Williams pears.
