] If you heat vinegar, it gives off pungent fumes that can make your eyes water, your nose run, and your throat 'catch'. Might be beneficial to someone whose breathing is constricted. I have never tried burning it , though.What, in the vinegar, would burn? The alcohol? The sugar?
Alcohol won't burn until it reaches 80 proof (ie, 40%), and even then not strongly. There certainly isn't that much of it in vinegar!
If I remember my organic chemistry properly, what makes vinegar vinegar is the acetic acid, which is surely what is being driven off when you heat it. I wonder if perhaps "burnt vinegar" was effected by quenching some heated metal in it? Isn't that how they made other "burnt" drinks--with a fireplace poker or equivalent?
