Peterson Smoking Pucks will work in nearly any type of smoker. Peterson Smoker Pucks' unique design allows them provide a longer lasting and more concentrated smoke. You only need to fill your smoker's chip pan one time. Peterson Smoker Pucks will begin smoking in 5 minutes in an electric smoker and will last for nearly an hour and a half. Three Peterson Smoker Pucks fit neatly in chip pans and they can be stacked to provide longer lasting smoke. Peterson Smoker Pucks can be used in gas and charcoal grills. Add one or two Pucks to your smoker box, or simply place them in the back corner(s) of your grill on the grate or in a tuna can, pan or on tin foil to keep from flame. Keep Pucks dry. They do not need to be soaked prior to use as do other brands. One bag of Peterson Smoker Pucks will smoke more than 3 times as much meat as a bag of conventional smoking chips.

Once you try the Peterson Smoker Pucks, they will remain the primary source for adding a wood smoke flavor to all of your favorite meats.
