For the Pork
1
Slice the pork into approximately ¼ inch thin cutlets. Poke the pork with a fork to make a bunch of tiny holes in the pork. Combine all the marinade ingredients together and marinate the pork for 2 to 24 hours. The longer the better!
2
Preheat oven to 500°F. Place the pork cutlets on a parchment-lined baking pan and place in oven. Immediately reduce heat to 325°F and cook for ½ an hour; basting often with the marinade. Remove from oven and cool. Chop the cooked pork into medium dice. Heat the peanut oil in a pan and sauté the garlic, ginger and white scallions in the oil. Add the diced pork and the remaining marinade. Simmer until the marinade is thickened. Toss in the green scallions. Let cool.
3
Alternate option: Instead of roasting, you may also grill the pork cutlets for a few minutes on each side, which will add the maximum smoky flavor.
For the Dough
4
Boil the water and milk with the butter and salt. Add the flour to the boiled milk mixture, stirring constantly over medium heat. Continue to cook until the dough forms a ball and pulls from the side of the pan.
5
Remove from pan and place in the bowl of an electric stand mixer fitted with the paddle attachment. Mix on medium-high speed. Carefully add the eggs all at once and mix until smooth. Take dough of mixing bowl and place on a floured work surface. Using a rolling pin, roll out dough vertically and horizontally until you have created a big square about an 1/8 of an inch thick. Cut 4 inch by 4-inch squares. Add a heaping tablespoon of the Char Siu to each square and roll it up. Place it on a parchment-lined sheet pan with the dough seam facing down and crimp the sides with a fork.
6
Preheat the oven to 400°F.
7
Brush with simple syrup (1/2 cup sugar and 1/2 cup water brought to a quick boil in a sauce pan), sprinkle sesame seeds and bake in oven until golden, about 20 minutes. Take out, let rest in cooling rack for a few minutes and serve hot.
Notes

For a vegetarian version, substitute the pork with tofu or a hearty vegetable like mushrooms or squash.
