Boil Sampaloc until prepared. Once prepared, wait for a few minutes or until it’s no longer hot. Then, extract Sampaloc juice from the fruit—filter beans and the skin.
Heat oil in a pot and saute chopped onion, ginger, and green chilies for 5 minutes.
Once the onion becomes soft, add the meat to the pot and then pour in the fish sauce. Cook for about 10 minutes while stirring.
Pour Sampaloc juice and bring it to a boil. Stir and simmer for 15 minutes. Skim the scum.
Add lemongrass, then cover the pot. Cook over medium heat and wait until the meat gets tender.
Put tamarind leaves or flower buds. Stir constantly and simmer for five more mins.
Transfer to a serving plate.
Serve while hot. Share and enjoy!
