It can be homemade just like in the old days using Everclear. But the dangerous part is evaporating the alcohol down. Dummies tend to use things with open flame/red hot coils to heat it. BOOM! Here in LA, there’s one of those fires at least once a week.
My days of fooling with that stuff are long past but I’ve always had patience.
I’d just put it in a tray in a warm (well-ventilated) place and let nature evaporate the hooch. No hurries no worries! :)
