Cranking your slow cooker to high will cook the contents more quickly, however you may want to try this only when you’ll be able to monitor the progress. Cooking on high all day may overcook the food and some foods will be more sensitive to high heat cooking than others. As you probably know, it’s the slow cooking that’s so effective on tougher cuts of meat. Some slow cookers have a special program that starts on high and moves later to a lower heat. You’ll want to read the directions on your slow cooker and do a little experimenting with what works best. Betty’s recipes have been tested for optimum results at the time and heat level provided.
