For the braising liquid
1. Combine the ground ginger, paprika, mustard powder and salt in a bowl. Mix well.
2. Heat the oil in a saucepan over a medium heat. When hot, add the shallots and sweat until very soft and caramelised for approximately 8 minutes. Add the garlic and continue to sweat for 1 minute.
3. Add half the spice mix – reserving the other half for a rub – and the rest of the ingredients to the pan and stir to combine. Bring to a simmer for 15 minutes then blitz with a hand-held blender until smooth.
4. Pass the liquid through a fine meshed sieve and set aside.
For the pulled pork
1. Season both sides of the steaks with the remaining spice mix. Sear in a hot pan (or place on a hot barbecue – see smoking tip, below) to colour both sides for approximately 1 minute on each.
2. Remove the steaks from the heat. Place the braising liquid in a large pan, add the seared steaks and bring to a simmer. Reduce the heat until the liquid barely simmers. Allow to cook for 90 minutes.
3. After the time has elapsed, allow the meat to cool in the sauce completely. Remove the steaks and place on a chopping board. Use 2 forks, as shown, to pull the meat apart until it is finely shredded. Place the shredded meat back into the barbecue sauce.
4. When ready to serve, warm the meat in the barbecue sauce by placing the pan over medium heat. Check the seasoning and adjust with salt and freshly ground black pepper if necessary. Warm the burger buns by placing them cut-side up in a warm oven or on a warm barbecue. Place some of the meat on the bottom half of the bun, add some slaw and place the other half of the bun on top.
