Chocolate Gravy
1/2-3/4 cup granulated sugar (to taste)1/3 cup Hershey's cocoa7 tablespoons flour (or Wondra)1 cup milk1 12 oz. can evaporated milk1 egg1 1/2 teaspoon vanilla
Mix flour, sugar, cocoa, egg and a bit of the milk in a separate bowl. Set aside.
In a pan sprayed with Pam, heat the milk until warm. Turn on medium heat. Transfer the flour and egg mixture to the saucepan.
Keep stirring as it thickens, so it won't stick or burn; reduce heat as necessary.
When it reaches a pudding-like consistency, remove from heat.
Stir in vanilla.
Gravy thickens slightly when removed from heat.
This is best prepared using an electric mixer or hand blender to help avoid any lumps.
