The electric smoker grill is far easier to use than its charcoal burning brothers. Charcoal is messy with creosote that takes elaborate cleaning before and after each use. Electric models are cleaner to use and easier to clean between uses. Most front opening models are easier to clean than a small refrigerator. Not having to lift the lid during cooking, as you do with a charcoal grill, allows the temperature inside to remain more constant. This makes for a much better final product.
An electric smoker grill does not require the constant temperature adjustments that charcoal grills require. It can be tricky to maintain the proper temperature in a charcoal grill or smoker. Electric models can be set to the setting you desire, and some models have a thermostat that will maintain a consistent temperature throughout the cooking process. This consistency in temperature assures that your food is done appropriately in the length of time called for in the recipe. That is helpful when there are hungry mouths waiting for you to finish cooking.
An electric smoker grill uses wood chips to provide the smoky flavor. Since the temperature in an electric unit is lower than with most charcoal fires, fewer wood chips can give the same smokiness. Most electric models seal more tightly, adding additional smokiness during the cooking process. The tight seal also retains moisture, giving the food the juiciness you desire in smoked and grilled foods. Pork is the most popular meat to smoke, but beef, poultry and even seafood are marvelous in electric units.
