Trim any visible fat from the meat. Set aside. In a small mixing bowl combine caraway seed, salt, and black pepper. Rub over meat.
In a 4- or 6-quart pressure cooker heat 1 tablespoon of the oil over medium heat. Cook meat until brown on all sides. Add more oil, if needed. Remove the meat and set aside. Drain off fat.
Place the rack in the pressure cooker. Return the meat to the pressure cooker and add the onion, water, and apple cider or apple juice.
Lock lid in place. Place pressure regulator on vent pipe (if you have a first-generation cooker). Over high heat, bring cooker up to pressure. Reduce heat just enough to maintain pressure and pressure regulator rocks gently; cook for 45 minutes.
Allow pressure to come down naturally. Carefully remove lid. Transfer meat and onion to a serving platter; keep warm.
Add apples to pressure cooker. Bring to boiling. Cover loosely (do not lock lid) and cook over medium heat about 5 minutes or until apples are crisp-tender. With a slotted spoon, remove apples to serving platter. Makes 8 main-dish servings.
