Sinigang - filipino beef soup

Season the meat with a little Salt and Pepper. I also add a little calamansi juice to add the sourness to the meat.
Take a large pot and sear all sides of the meat in the pot.
Once all the meat is cooked, add the water and soup mix.
Bring to a boil and than bring it down to a medium-low heat.
Cover the pot and let it boil for a couple of hours until it is tender *you could use a slow cooker also
Once the meat is quite tender add the potatoes.
Cook until the potatoes are tender and add the remainder of the vegetables.
Add more lemon or calamansi juice to your taste.
Serve over rice
* Generally, you could add patis (fish sauce) during the cooking process but I like to let everybody add to their taste.
