This is the authentic way to cook lechon paksiw. An authentic Lechon paksiw doesn’t need to add soy sauce or otherwise it will turn like adobo. Believe me, I tried their (famous pinoy website) recipe some years ago and it was an epic fail to my taste bud. I should have listened to my mama. Paksiw is just lechon sauce plus vinegar (for obvious reason it is called Paksiw..hehe) and essential seasoning. You may add soy sauce if you like but only 1 teaspoon just to enhance the flavor and color.. I hope your family enjoy this delicious recipe. Happy cooking!
