Get creative with pork sinigang cut by simmering it on low heat for an extended period of time. With layers of fat keeping it moist, cooking it low and slow allows the flavors to seep in, resulting in the perfect sinigang. Slurping the sour broth of the pork sinigang is indeed SOOTHING and SATISFYING. Put a spin on basic sinigang by adding tomato sauce and paste and allowing it to reduce to a thick simmered soup.
