What is it? True liquid smoke is produced by the method of destructive distillation. The process consists of the burning wood chips (generally Hickory), capturing the smoke, condensing the smoke into solids or liquids, and then dissolving the smoke solids in water. In 1895, Ernest H. Wright introduced the first liquid smoke for sale on the American market. According to the Wright’s Company, now owned by B&G Foods, to this day their liquid smoke is the only brand with no added preservatives, sugars, or sodium …and yes, it is Vegan! If you want to experiment with liquid smoke, and you’re a Veg, you will have to ignore the picture on the label of the bottle of a cow’s rear end being fried on the grill.
