Creamed Chipped Beef (aka SOS or S*** On A Shingle)

I got this from a Pennsylvania Dutch group on Facebook: https://www.facebook.com/photo/?fbid=5198166390196491&set=pcb.2109358582567384See Ingredients in the Directions.

Brown 1 lb. dried beef in 1/2 cup butter. (The ones I saw online are from Armour and Hormel, but I am sure there are others.)
Stir in 6 Tbsp. flour.
Stir until browned.
Add milk to desired thickness.
Season with salt and pepper.
Add a tiny bit of cayenne, just a couple of small pinches.
Serve on toasted bread.
