Should I use pork shoulder or pork butt?
Either works great. In most grocery stores, pork butt is actually part of the shoulder. Both have enough fat and connective tissue to turn tender and shreddable under pressure. Look for a cut with good marbling and a fat cap if possible.
Do I really need to cut the pork into chunks?
Yes for this timing. A whole 3 to 4 pound roast usually needs more time than 60 to 70 minutes to shred properly in the Instant Pot. Cutting it into 2 to 3 inch chunks gives you more surface area for seasoning and helps it get truly pull-apart tender on schedule.
Can I cook it from frozen?
It is possible, but not my first choice. You cannot apply the rub well, and you may get uneven texture. If you must, pressure cook a frozen pork roast longer (often 60 to 75 minutes per 3 pounds, depending on thickness), then season and broil after shredding. For best flavor, thaw overnight in the fridge.
Why is my pulled pork tough?
Tough usually means it is under-cooked. Pressure cooking needs enough time for collagen to break down. Put it back in for 10 to 15 minutes with a natural release, then try shredding again.
Do I need liquid smoke?
Nope. This is a cozy, weeknight pulled pork. If you love a hint of barbecue vibe, add 1/2 teaspoon liquid smoke to the cooking liquid, but keep it light.
How do I keep it from tasting bland?
Two big fixes: salt and acid. Salt the pork properly, and finish with a splash of apple cider vinegar or pickle juice in the sauce. Also, taste the reduced cooking liquid before tossing it with the meat.
What if my cooking liquid is greasy?
Skim the fat off the top, or chill the liquid briefly so the fat rises and solidifies. You can also pour it into a fat separator if you have one.
