Well, you do know everyone's mama's a little different just like their gravey. So I'll just tell you how I make mine.
Fry your meat in a good skillet, cast iron is great. When you take the meat out leave some grease or add some oil. Turn to medium heat and stir in flour. Stir it until it is smooth (you need approximately the same amount of oil as flour...say 1/4 cup for a big bowl of gravey). Stir it over med high heat until the flour turns brown.....before it turns black stir in water until smooth and just a little thinner than you want your gravey to be. You can use part milk (I do and I add a dash of soy sauce to get the color right again). Salt and pepper to taste. If it tastes flat or you didn't have some good meat to start with you can add a little dried beef boullion to it. Cook and stir until it is the right thickness...adding water if it gets too thick.
Sausage gravey: fry the sausage, leave it in pan and make the gravey in that skillet.
Red eye gravey: fry country ham, remove from skillet and add water. If you want it thick add flour first then the water...it usually doesn't need any seasoning.
Hope this helps.
PS.. If that doesn't work for you, bring the quail, I'll make the biscuits and gravy and get hubby to make the smashed taters!
