3 lbs beef bones
1 large onion, cut into 4
1 pack tamarind sinigang mix
salt and ground pepper to taste
Boil enough water in a big pot. Once water starts boiling place the beef bones. Bring to boil for few minutes, remove meat and discard water.
Rinse pot and boil enough water again. Once water starts boiling add the beef, lemon grass stem and onion. Keep boiling till beef is fully soft. (faster if you use pressure cooker)
Once beef is fully cooked add langka and ground pepper. Boil till langka is fully cooked. Season the broth with the tamarind mix and salt to taste. Simmer for few more minutes then add the petchay. Bring to a boil for few minutes, remove pot from the heat to avoid the vegetables from over cooking. Serve hot,
