To make gravy, Set the pan on your stove burner. Add 1 c. water to the pan. Scrape any dried on drippings off the bottom of the pan. Turn to high. Pour flour or cornstarch into a bowl or glass measuring cup, slowly add the second cup of water, stirring to remove lumps. Pour into pan on stove. Stir with a whisk to combine. Turn to medium and simmer until thickened. (For thicker gravy, add more flour or cornstarch. For thinner gravy, add more water. If you need more gravy, add more of both by stirring together first to avoid lumps and then adding to the pan.) Salt and pepper to taste.
