This recipe benefits from added PG I'm not exactly sure why because I'm not a chemist but there is a difference when I made it max VG. Steep time is minimum 2 weeks.
Kinda bland - maybe just not my flavor - the butterscotch FW might be better replaced with butterscotch candy or maybe caramel pecan than the butterscotch FA - I think Butterscotch FW might not be strong enough to stand up to the cinnamon and banana.
