3–4 cups turkey juices/drippings
1/4 cup flour or cornstarch
Salt, pepper to taste
Pour turkey juices/drippings into a saucepan. Whisk in flour. Add salt and pepper. Simmer for about 15 minutes, stirring once in a while until it is the right consistency.
If the gravy is too strong or you need to stretch it just a little, you can add a small amount of water. Another way I used to make turkey gravy (either way works) is to dissolve the flour in 1/2 cup of cold water and then whisk it into the turkey juices.
