The Rival Company introduced the Crockpot slow cooker in the early 1970s. Using low-wattage electricity, the slow cooker uses an indirect heat source to braise food in its own juices. Without a flame, you can place ingredients into the ceramic pot to stew all day unattended. Stirring the food is discouraged because heat is lost when the lid is opened. Tougher cuts of meat, like pork shoulder, are ideal for slow cookers. They break down during the six to eight hours of slow cooking to create tender morsels. Follow a few easy steps to cook pork shoulder in your slow cooker.
Mix together your salt, black pepper, and dried oregano in a mixing bowl. Coat the pork shoulder pieces with your mixture.
Place coated pork shoulder into a clean slow cooker. Add onions on top of pork. Cover the slow cooker with the lid and be sure it is on securely. The slow cooker uses the low heat to cook, so a tight lid is important.
Turn the slow cooker to the low setting and cook for 6 hours. Remove the cooked pork with a slotted spoon to a cutting board. Discard onions and break apart pork with your fingers.
Serve pork with cilantro and avocado on a serving platter. Use tortillas and salsa to make tacos with the pork.
Experiment with different spices for your pork shoulder cooked. You can also try different meat or legumes to make stews and soups.
Use caution when handling the hot ceramic pot while it is cooking.
