Lazy Kettle Brand All-Natural Hickory Liquid Smoke is real smoke. Hickory is burned, and the smoke is liquified, filtered, and bottled. Use it to add a wonderful, smokey flavor to all your favorite foods. If you are cooking indoors, but want the flavor of the open grill, just add a few drops of smoke on your meat. Or, just add it to your store-bought barbecue sauce, marinade, ketchup, or dressing.
