Spread your ground beef or whatever in a shallow pan or on a fine screen and place into your smoker. Smoke for 20 minutes to 2 hours. Hickory and Alder fuels are zippy... Apple is a bit more mellow.. and cherry will hit'em where it counts. Take your pick. Then use the smoke flavored hamburgers or whatever in your regular way. Shorten your cooking time by 20-30%. (Use cherry fuel when making chili; it really fits).
