The best device to slow cook a 4lb pork shoulder depends on your personal preferences, cooking style, and the desired outcome. Each method you mentioned has its advantages, so let's briefly explore each one:
Crock-Pot or Slow Cooker: This is a classic and convenient option for slow cooking pork shoulder. Crock-Pots are designed for long, slow cooking at low temperatures, which helps break down the tough fibers in the pork shoulder and results in tender, flavorful meat. It's a "set it and forget it" approach, making it ideal for busy cooks or those who want an easy and hands-off cooking experience.
Sous Vide: Sous vide cooking involves vacuum-sealing the pork shoulder in a plastic bag and cooking it in a water bath at a precise and consistent temperature. This method ensures precise doneness and even cooking throughout the meat. Sous vide is excellent for achieving a perfectly tender and juicy pork shoulder, but it requires specialized equipment and more time compared to other methods.
Oven: Slow roasting in the oven is a reliable method for cooking pork shoulder. It involves cooking the meat at a low temperature for an extended period. While it may not be as hands-off as a slow cooker, it allows for better browning and caramelization on the meat's surface, enhancing flavor and texture.
Induction Stove Top: Induction stoves can provide precise temperature control, making them suitable for slow cooking. However, cooking a large pork shoulder on an induction stovetop might be challenging due to limited pot size. If you have a large enough, heavy-bottomed pot or Dutch oven, you can use the induction stovetop to slow cook the pork shoulder effectively.
Something Else: There are other options for slow cooking, such as electric roasters or even outdoor smokers if you prefer a smoky flavor.
In summary, each method can yield a delicious slow-cooked pork shoulder, so the choice depends on your equipment, cooking preferences, and the amount of hands-on attention you're willing to invest. If convenience is a priority, the Crock-Pot is an excellent choice. For precise and tender results, sous vide is a great option. The oven offers a balance between hands-on cooking and flavor development, while an induction stovetop can be useful if you have the appropriate cookware. Consider your needs and available equipment to decide which method suits you best.
