A slow cooker is a kitchen appliance that allows you to cook food at low temperatures over an extended period of time. It's also known as a crockpot or an electric pressure cooker, and it's designed for dishes that require long, gentle simmering. The slow cooker does all the work - it heats up the ingredients, then maintains a consistent low temperature so that the food can slowly cook without any additional attention needed from you. This makes it perfect for busy people who want to come home to a delicious meal ready to eat or for anyone who wants to enjoy a slow-cooked dish like pulled pork or beef stew.
