I had never heard of such a thing, I, being like any woman, (a chocolate lover) was curious, I quickly ladled myself some of this delectable deliciousness and it was game on. I spent years trying to get the exact recipe from grandma, but alas, just like my mother-in-law, she uses no recipe. Its just all in the "feel" of the sauce.... well and good unless you are trying to learn to make the stuff!
I have played with this over the years and made some good, some not as good batches. I too rarely use a recipe these days, its all in the "feel" but I did pay close enough attention when my daughter began asking how to make this goodie so that she was able to re-create it as well.
Here is the coveted Chocolate Gravy:
1 can evaporated milk (can sub whole milk or cream but it won't be as rich)
2 cups sugar
1/4 cup baking cocoa
1/2 tsp vanilla
1 T real butter
3 cups flour
2 and 1/4 cups milk
3 T sugar
6 T melted butter or olive oil
3 T baking powder
1 and 1/2 tsp salt
Mix all together and pour by 1/2 cup measure into hot waffle iron.
