Step 3: Remove round from marinade. Discard marinade. Grind beef suet with salt and spices. Make deep holes with sharp paring knife in both sides of round and stuff seasoned suet into holes. Tie spiced round in heavy pudding bag or cheesecloth. (Tradition would require an old pillowcase, linen or cotton, no synthetics.) Cover round with water and boil in large covered pot 15 minutes per pound. Cool and refrigerate another day before serving.
Thinly slice spiced round horizontally. Keep bone in round as it helps in carving. Serve on nut bread with horseradish sauce and catsup. Note: Keeps in refrigerator for 1 week. Freezes well. Serves 40
