If you want to make crispy crackling and you have rind on pork chops, take a sharp knife and cut off the pork rind. Trim up the fat, leaving around 5mm (¼") on the pork chop and 3-5mm (⅛-¼) on the rind.
Rub the pork rind with the oil and then season generously with salt; it needs a lot of salt!
Heat a frying pan over a medium-high heat and add the pork rinds, skin side down and cook for 5-7 minutes. You will need to stand there and press down the rind to stop it from curling and ensure that it browns well.
Flip the pork rind and then cook the fat side for 2 minutes, then transfer to an oven and cook skin side up for 30 minutes at 200°C or 395°F.
Shred the cabbage into 5mm (¼") strips.
Season the pork chops with salt.
Set the Instant Pot to saute mode at the high setting, and when it says hot, add the pork chops one at a time and sear well on both sides. This will take 2-3 minutes per side per chop. Then sear off the fat by holding the chop vertically with some tongs, for another minute or two. Set aside the pork chops.
Pour the cider and chicken stock into the pot and then stir, scraping the base of the pot to ensure that you are removing any crispy bits.
Turn off saute mode, then stir in the brown sugar, cinnamon stick and black pepper.
Add the red cabbage, then place the pork chops on top of the cabbage.
Pop on the lid and seal it, cook on high pressure for 4 minutes, then allow the pot to rest for 5 minutes before releasing the pressure.
Whilst the pork is cooking, mash the softened butter with the flour.
Remove the pork chops and set aside to rest, then remove the cabbage with a slotted spoon and place them in a bowl covered with foil to keep warm.
Turn the Instant Pot to saute mode on the high setting and wait for the juices to come to a rapid boil.
Once the sauce is boiling, whisk in the butter and flour mix and cook for 2-3 minutes until the sauce begins to thicken.
