Searing meat does add flavor and a nice crispy texture, but it's optional when using a pressure cooker. Honestly, this pork is really good without bothering to sear it first. It makes the recipe much faster and easier if you can just throw the meat in the pot! Plus, the crispy texture from browning the meat softens considerably when the meat cooks. A pressure cooker traps moisture, which makes the meat soft and tender. If you would like to sear the pork butt, then add 2 tablespoons of oil to the pot first. Sear each chunk of pork for 3 to 5 minutes, until nicely browned. Then deglaze the pot with a little bit of water or broth the make sure bits of burned meat don't stick to the pot. From there, you can start the recipe below.
