In my family we have never been able to agree on gravy. My dad likes his made with the giblets and everything, all ground up in the food processor, and my mom likes hers clear (just the drippings from the turkey, with the fat removed). I like the creamy kind (somewhere in between, I guess), which is pretty easy to make.
1 Tbs butter
2 C turkey drippings
3 Tbs flour
Melt the butter and whisk in the flour to thicken. Gradually add the drippings, stirring constantly until thick and creamy.
