Deglaze pan with the Sherry, scraping the bottom of the pan with a wooden spoon. Add lentils and chicken broth to the pan. Bring to a simmer, cover the pan and cook for about 45 minutes, or until the lentils are just tender. Check the lentils occasionally making sure they are not boiling. Adjust the heat as necessary. I usually have the heat set to low allowing the lentils to simmer gently.
The lentils are done when just tender. You may uncover the pan for a few minutes if there is too much liquid (the lentils should not be dry). Keep in mind the lentils will absorb some of the liquid once refrigerated.
