When oil is hot, wisk in flour and continue to wisk until this roux gets to the color of peanut butter or a little darker. Be careful. Once it begins to brown it will darken until it is burned. If this happens, start over.
When roux is right darkness, remove from heat and pour in broth while wisking. It will blend and become smooth. Add beef dripping now if you have it.
Return to medium low heat and add the rest of the ingredients and stir until the flavors are blended.
