Kosher Stuffed Derma

Makes: 6 servings. Wash casings in cold water and cut into 12 inch lengths. Tie one end of each length tightly with white sewing thread. Turn casings inside-out. Combine flour, matzo meal, seasonings and schmaltz or suet. Fill each casing loosely with this stuffing and tie the remaining end. Drop into rapidly boiling water and boil 10 minutes. Drain. When cool enough to handle, scrape fat off the casings with the dull edge of a knife. Drop into rapidly boiling water (about a gallon) to which has been added 1 tablespoon salt and at least 1 teaspoon pepper. Reduce heat and simmer uncovered for 3 hours. Remove from water. Brown for 1 hour around a roast or roasting poultry. (You can also refrigerate and then slice pieces about 1 inch thick and fry them--on both sides.)
