Grandma's Sausage Gravy

My Grandma was born and raised in the Tobacco fields in the hills of Tennessee, and the first time I met her in the mid 1960's, she had raised 12 kids, still cooked on a wood stove, bathed in an aluminum tub, and used an outhouse. Coming to visit from the very modern California, my sister and I couldn't figure out how to flush the outhouse. Grandmas cooking was more delicious that anything I'd ever had, her Biscuits and Gravy were not like anything I'd ever tasted. Eventually, she moved to California, and as the years went by, she taught us her secrets, just plain, good ol' home cooking. She said she just did with whatever she had on hand.

I have tried every kind of sausage that I can find to see how it tastes with this gravy, our local grocery store, Leekers, makes their own Country Sausage, it is by far the best, but, J.B. Rice is pretty good, and of course there is Jimmie Dean, but, as my husband says, Dean has too many "Noogies", small chunks of gristle. Any kind of breakfast sausage will do.

Sausage, you can decide how much you'd like to use, as Grandma said, it depended on how the money was to how much sausage she used.
White Flour
Milk
Salt
White Pepper

Here goes:
Brown Sausage, preferably in an iron skillet, don't drain grease off.
Sprinkle enough flour on sausage to to make an even layer over all sausage
Stir with wooden spoon until all white is gone, this is important, this is what makes what some call a "roux".
Pour enough milk over the mixture to just cover the sausage, with medium heat, continue to stir slowly until the mixture thickens and gets a shiny glossy look. Adjust heat while stirring as needed to not scorch the bottom of the gravy. Salt and pepper to taste.
I use whatever biscuits are available, but, I slather them in butter before I ladle gravy over them. I asked my mom why Grandma used white pepper instead of black, she said it was because the black pepper reminded her of mouse droppings! So, there you have it, very simple, not much measuring, and people young and old tell me it's the best gravy they've ever had! My son's college friends ask if they can come home with him for gravy, so, that in itself, makes it worth making! I can still see my grandma telling my step-dad after he praised her for her gravy the first time he tried it saying in her fine Tennessee twang "Oh, shoot, it's just gravy"
