1
Drape the bacon in a single layer on the bottom of a pressure cooker. Press the "Sauté" button (if your cooker has one) and in about a minute, your bacon will start sizzling. (If you're using a stovetop pressure cooker instead, line it with 3 pieces of bacon, crank the burner to medium, and start frying your bacon.)
2
Cut the pork shoulder into 3 equal pieces. I normally cut out the piece with the bone first, and then cut the 2 other pieces to match the first.
3
If you've got some garlic on hand, use it! With a sharp paring knife, stab a few slits in each piece of pork, and tuck in the garlic cloves.
4
Sprinkle the salt evenly over the pork. As you're seasoning the pork, you'll hear the bacon sputtering in the pressure cooker. Don't forget to flip the slices, and turn off the heat when the bacon is browned on both sides.
5
Place the salted pork on top of the bacon, keeping the meat in a single layer. Pour in the water.
6
Do not forget this step: With a pressure cooker, you have to add some liquid for it to work properly. Check your manual to see what the minimum amount of liquid is for your particular model, and adjust accordingly. (After some digging and experimenting, I discovered that 1 cup of water is perfect for this recipe in my Instant Pot.)

Next, cover and lock the lid. If you're using an Instant Pot, select the "Manual" button and press the plus button until you hit 90 minutes. For an electric pressure cooker, set it for 90 minutes a high pressure. If you're using a stovetop pressure cooker, you won't have to worry about pressing all those fancy buttons. Just cook on high heat until high pressure is reached. Then, reduce the heat to low to maintain high pressure for about 75 minutes.
8
When the pork is finished cooking, the Instant Pot or electric pressure cooker will switch automatically to its "Keep Warm" mode. If you're at home, press the "Keep Warm/Cancel" button to turn off the cooker and let the pressure come down naturally quicker. If you're using a stovetop pressure cooker, remove the pot from the heat. In either case, let the pressure release naturally (which will take about 15 minutes).
9
Once the cooker is depressurized, check that the pork is fork-tender. If the meat's not yet fall-apart tender, you can always cook the pork under high pressure for another 5 to 10 minutes to get the right texture.
10
Transfer the cooked pork to a large bowl and taste the cooking liquid remaining in the pot. Adjust the seasoning with water or salt if needed.
11
Add the cabbage wedges to the cooking liquid. Replace the lid and cook the cabbage under high pressure for 3 to 5 minutes. When the cabbage is done cooking, activate the quick-release valve to release the pressure.
12
While the cabbage is cooking, shred the pork. Once the cabbage is cooked, pile it on your shredded pork.
