Barbecued Country Ribs

In a large resealable plastic bag, combine the flour, garlic powder, salt and pepper.

Add rib pieces; shake to coat. In a pressure cooker, brown meat on all sides in oil; drain.

Combine the water, ketchup, chili powder and hot pepper sauce; pour over ribs.

Add onion. Close cover securely; place pressure regulator on vent pipe. Bring cooker to full pressure over high heat. Reduce heat to medium-high and cook for 15 minutes. (Pressure regulator should maintain a slow steady rocking motion; adjust heat if needed.)

Remove from the heat; allow pressure to drop on its own. Skim fat from sauce if necessary and serve with ribs if desired.
