Place Sichuan peppercorns, coriander seeds, and star anise in the middle of a 6”x6” piece of cheese cloth.
Fold it over like so.
Tie it into a knot. This is also a great way to wrap up a bud if you don’t have baggies or a flour tortilla.
Heat up cooking oil in a Dutch oven over medium high heat. Add in the pork shanks. Sear on both sides for 3-4 minutes.
Pour in the water along with the garlic, ginger, green onion, cinnamon stick, five spice powder, and the cheese cloth spice sack. Bring to a boil. Cover. Reduce the heat to low. Simmer for 40 minutes.
Add in th soy sauces and palm sugar. Cover. Turn heat up to medium high. Simmer for an hour.
Add in a can of black beans with it’s liquid. Cover and continue to simmer on medium high heat for another hour.
The liquid at this point should’ve reduced by more than half. If there is more liquid in the pot then that, uncover and continue to simmer for another 10 minutes.
