Make Ahead Turkey Gravy

I always make my gravy ahead of time for Thanksgiving and I make a lot of it.   Gravy makes everything better.  I buy lots of turkey parts and make stock with them.

 Then, the day that I make the gravy all I have to do is melt some butter in a heavy pot.

 Add some flour.

 Whisk it while cooking it for several minutes.

Then slowly start adding the stock.  I wait until it begins to thicken and then add more stock.

 Taste it for seasoning and adjust it as needed.  I already seasoned the stock so all the gravy really needed was some chopped parsley. This will be placed in a slow cooker on the Thanksgiving buffet so it will stay warm.
