If using canned pears, do not cook them first; simply add the sugar to the drained, cubed pears in the skillet to caramelize.
For best flavor, use ripe but firm fresh pears such as Bosc or Anjou.
This tart can be stored in the refrigerator for up to 3 days. Reheat gently in the oven or microwave before serving if desired.
