Do people for reals buy HFCS for home baking? Like you can just go buy a jug at the grocery store? I've seen it in ingredients lists of packaged foods, but I've never seen the stuff itself IRL. (Gonna assume it looks roughly like syrup. Corn syrup maybe.)

Who is using Hydrofluorocarbons in their cooking? That's probably a bad idea. Heat plus HFCs is how you wind up inhaling hydrofluoric acid.
