I'm Marshall brain. A listener wrote into ask what is liquid smoke? You may have seen liquid smoke called for in certain recipes, but what is it. Liquid smoke is literally liquefied smoke. In a prior podcast, we talked about what smoke is. It is volatile hydrocarbons that evaporate from wood when you heat wood up. What this means is that by cooling smoke, you can cause the hydrocarbons to condense. What you get is a dark, sticky liquid that contains
all the flavors of smoke. If you says that condensate, thin it out a little, and put it in a bottle, you have liquid smoke. The process starts by taking wood chips or sawdust, putting them in a big metal container, and then heating it. The heat evaporates the volatile hydrocarbons. Then you run the smoke into a condenser, where cold coils caused the smoke to turn back into liquid form. Do you have any ideas or suggestions for this podcast? If so, please send me an email at podcast at
