Grandma's Chocolate Gravy Recipe

My grandmother never actually wrote down this recipe, saying that cooking was better done by "feel".  Luckily, a close family friend sat in the kitchen and watched her make it, writing as she cooked, a few years before she passed.  Here is just one of her gifts to the world:

Grandma's Chocolate Gravy

Ingredients:

2 1/2 c Flour
1 1/2 c Sugar
1/2 c Chocolate powder
1 1/2 c Water
1/2 - 2/3 c Milk
1/4 t Salt
1 qt Milk

Directions:

Add first 6 ingredients to saucepan and put on medium heat.
Stir constantly.
Once it starts bubbling, begin adding the quart of milk in small increments until it's all added while continuing to stir CONSTANTLY.
When gravy is almost a pudding consistency, it's done.
Turn off the heat.

Thank you!

I hope you enjoy it!
