The LOW setting is about 200 degrees, and the HIGH setting is about 300
degrees. Note that both of these temps are well above the minimum safe
temperature of 140 degrees.
Only fill the crockpot one half to two thirds full. The foods will not
cook properly if the appliance is filled to the brim. If the food and liquid
level is lower, the foods will cook too quickly.
Foods cooked on the bottom of the slow cooker cook faster and will be
moister because they are immersed in the simmering liquid.
Don't lift the lid to stir, especially if you are cooking on the low
setting. Each time you lift the lid, enough heat will escape that the
cooking time should be extended by 20 minutes to half an hour.
