Add in the evaporated milk and continue cooking, stirring occasionally until thickened. (gravy should coat the back of a spoon). If too thick, thin by adding a water a little at a time until you reach the desired consistency.
Separate dough into 10 biscuits and cut the biscuits into quarters. Place biscuits inside prepared baking dish.
Pour gravy evenly over the top of the biscuits.
If preparing the day before, allow to cool for about 30 minutes, cover with foil and place in refrigerator until ready to bake.
When ready to bake, preheat oven to 350 degrees and bake, covered for 20 to 25 minutes. Uncover and continue baking for an additional 10 to 15 minutes or until tops of biscuits are light golden brown.
