T.C.
I use the drippings from my meat and add Crisco if need be. I allow it to get warm and then add my flour slowly. I sift/mix it in to the drippings slowly. I then take either water or milk (sometimes half and half) and pour, whichever one I choose, slowly into my flour and drippings. I may add more liquid to get the consistency I prefer. Again stirring slowly until it becomes smooth and without lumps. I add garlic and salt to taste.
Hope this helps! :-)
