Man, this sounds and LOOKS awesome!
I don’t think my wife would be happy with all the flame play in the kitchen, tho alcohol flames are fairly cool.
Still did you notice he kept his gin in an ice well? I thought for sure there might be enough thermal shock in that long pour to crack the mixing glass!
Of course I use a Cobbler shaker, which is all metal, so no worries there so long as I don’t burn my house down!
