In the USA, most people call these electric cookers crock pots, whereas in the Great Britain they are normally called slow cookers. Crock pots by Rival, DeLonghi, Hamilton Beach, Cuisinart and Toastess are particularly good examples of advanced crock pots. Some of these crock pots are programmable, which allows the cook more flexibility that the slow cookers of twenty years did not.
I have been on the hunt to get great slow cooker recipes for a long time, and I can not seem to get something which i like.
As long as you own a 3 quart slow cooker, you probably are aware of how helpful and convenient it can be. You might, though, be a bit uneasy leaving it on all day to cook. This is the best way to make good foods in the crock pan, so as long as you are scared to leave it on (possibly fear a fire) than you cannot use it properly. You may want to learn more about safety and your crock pan before leaving it on all day.
