Won’t cooking it evaporate all the alcohol?
The cooking is done in a SEALED mason jar, so as it boils, the booze re-circulates, and you lose none. I say to cool it before opening and straining for the same reason, to prevent gas-off of the booze. Food grade ethanol is expensive here in Canada (48$ a liter!!!), so until I can brew my own, I treat it like gold. It costs me more than the pot! Heating up the booze makes it more aggressive of a solvent, and helps strip the THC.
