Add the water or chicken broth and star anise (if using). Bring the mixture to a boil.
Lower the heat, cover the pot, and let the pork simmer for 45 minutes to 1 hour, or until the pork is tender and the sauce has thickened.
Stir in the sesame oil and let it cook for another 5 minutes.
Garnish with chopped spring onions if desired and serve with steamed rice or your favorite side dishes.
Enjoy your delicious braised pork belly!
