Drawn Butter Gravy for Calf's Head
Ingredients
Directions
Rub the butter into the flour until well combined.
Pour in the milk or water while stirring continuously.
Bring the mixture to a boil, then remove from heat to prevent oiliness.
Chop a little of the liver and brains, then add to the gravy.
Arrange the large pieces of the calf's head on a platter.
Pour the gravy over the meat and garnish with parsley and hard boiled eggs.
Remove the skin from the tongue before serving.
