Turkey Gravy

1/3 cup chopped onion
1/3 cup butter
1/3 cup all-purpose flour
1/4 teaspoon black pepper
1/4 teaspoon celery seed
1 3/4 cups Turkey drippings
2/3 cup buttermilk

In the saucepan over medium heat, cook onions in butter until soft and translucent.

Stir in flour, pepper, and celery seed.

Combine Turkey Drippings and buttermilk in pour-able container, like a large measuring cup.  Slowly stir into onion mixture with a whisk.  Be careful it likes to slosh.  

Simmer over medium-low heat until thick. Remove from heat.

Note: If you are not using turkey drippings where you used Seasoning Salt on the turkey then add 1/2 teaspoon salt to the flour mixture in the instructions.
