Raisin Gravy

One of my very favorite things of all time that my Mama used to make for me was her raisin gravy. Don't gross out, it's heavenly. Thing is, I've watched her make it a million times, but I never actually asked her how she did it. So, I've got to experiment and see if I can attempt to match it. 
My lovely sister, Cindy (who also never asked how she made it), found a recipe for raisin pudding. I made it tonight and it turned out so yummy. Here it is:

So, I guess my first challenge to myself is to tweak this to match raisin gravy as much as I can. It's a good thing Shane likes raisins....
