I love chipped beef on toast.
I make it now, or a variation of it. I use good pastrami, half and half, butter with flour in it to thicken it and put a little mustard in it for a little kick and add a little good beef bouillon type product for extra flavor with a little salt and pepper. MM MM good!
I seem to remember the old recipe for creamed chipped beef.
4 oz beef
4 Tab flour
4 Tab fat( butter for me!)
gently fry it to a gooey mess and slowly add...
4 cups of milk
I never had to look up a recipe
