Step 1: Prep the pork: Rinse and dry the pork shoulder, then rub it all over with salt and pepper.
Step 2: Add the rub: Mix oregano, cumin, and olive oil, then rub it all over the pork like you mean it.
Step 3: Into the slow cooker: Place pork in the slow cooker, fat side up.
Step 4: Add everything else: Throw in onion, jalapeño, garlic, and pour over the orange juice. No need to be neat here.
Step 5: Slow cook: Cook on low for 10 hours or high for 7 hours. This is the part where you do literally anything else.
Step 6: Shred the pork: Remove pork, let it cool slightly, then shred using two forks. Try not to snack too much during this step.
Step 7: Save the juices: Skim excess fat, and if there’s too much liquid, reduce it slightly. This is flavor gold.
Step 8: Crisp it up (optional but important): Heat oil in a pan, spread pork, drizzle juices, and let it crisp up. Don’t stir too soon. Let it get golden.
Step 9: Repeat if needed: Do this in batches so it actually crisps instead of steaming.
Step 10: Serve: Drizzle with extra juices and serve hot however you like.
