Place the pork loin roast in a sturdy pot that allows just enough room to easily turn it. Pour in milk to a level that covers 3/4 of the roast. Sprinkle with salt, pepper and nutmeg. Add peeled garlic cloves. Turn the roast over in the pot.
Place the pot on medium heat and bring to a boil. Reduce heat so that milk is just barely boiling and place the lid on the pot leaving a small opening. Simmer at this very low boil for 1 1/2 hours or until the roast is cooked through. Turn the roast several times during the cooking.
When it is done cooking, remove the roast from the pan and cover the meat to keep it warm.
Fish out the cloves of garlic from the cooking liquid and strain the rest of the liquid into a blender. Add the cloves of garlic and the bread to the blender and then blend until smooth. Season to taste with salt and pepper. You may want to return the sauce to the stove (in a clean pan) for a few minutes to thicken it further.
To serve, slice pork roast and pour sauce on top.
Makes 6 - 8 servings.
