I should have specified that I only
make and consume what we call
cream gravy made with milk.
Cream gravy , uuuummmmm GOOD.
I at times, when I make a Pork or Beef roast I add bouillon and cream, either half and half or heavy, to the roast pan after approx. half of the cooking time is done.
Often I also add sliced potatoes, thin sliced at the same time and let it cook till it is/are done, and that is some of the best potatoes and gravy in the world.
My one grandmother almost always put some cream or from the barn milk in her gravy.
When we cooked steak fifty yeas ago in the old gas range, the broiler had a grease drippings pan and when the stake was done, mom and dad would put the drippings
pan on the table and we would dip home-made bread into that, Manna from God.
