Have the butcher cut pockets in the pork chops. Preheat the oven to 350°F.
In a skillet, heat the butter and sauté the onions and garlic about 5 minutes. Remove from heat. Combine with the crumbs, salt, caraway seed, parsley, egg and water and mix well. Stuff the chops with the mixture, closing the openings with toothpicks.
Place the chops in a baking pan and season to taste with additional salt and pepper. Cover closely and bake 30 minutes. Uncover and continue baking until brown and tender, about 30 minutes longer. Remove chops to a heated platter.
Pour off fat from the pan. Add stock to the pan and bring to a boil. Thicken with flour mixed with a little water.
