Basic Pan Gravy
Have your ingredients ready with everyting at your fingertips.
Use a large serving spoon.
Add liquid gradually and stir quickly (eliminates lumps).
Keep heat on medium (too hot causes gravy to thicken too quickly).
Gravy keeps cooking and thickening even after it's removed from the pan. Pour it up just before you think it is thick enough(Experience is the best teacher).
If gravy is too thick, thin with a little warmed liquid and reheat.
End results... you should have a nice gravy and no lumps! :)
