(Day ⅓) Prepare the ginger by peeling the skin & letting it sunbathe overnight. This removes all the water so the spice from the ginger is extra concentrated.
(Day ⅓) Place the pork knuckles in a bowl, and rinse with water multiple times. This will wash out all the guts and ensure your pork is extra clean.
(Day ⅓) In a large pot, add the pork knuckles, some ginger slices (optional) and a cup of rice vinegar. Fill with water so that the pork knuckles are all covered, and bring to boil for 5 minutes.
(Day ⅓) The pork knuckles will have a translucent color, and put them in the fridge overnight.
(Day ⅔) Grab the sun-dried ginger, and chop them into chunks. Using the side of a knife, smash them into pieces. Give it a good whack!
(Day ⅔) Pour a quarter of the Chinese vinegar sauce into a large pot along with your smashed ginger. Bring to a boil for 5 minutes, and leave the pot overnight on the counter.
(Day 3/3) Take the pot from overnight and add in the pork knuckles from day 1 and all the peeled eggs (optional). Pour the remainder of the Chinese vinegar sauce.
(Day 3/3) Bring the pot to a boil, and you're ready to serve.
