i had about 50ml of USA mix 24mg from Rocky Mountain Vapor that i was afraid was going to go bad. i remembered i had some rum and butter extracts left over from chritsmas and thought what the hell. just to try i used 3ml usa, 1.75ml rum, and .75ml butter. it turned out pretty good. its only about 14mg nic but has good vapor and taste using the usa gives it a decent TH. i used McCormicks because thats what i had. im not a DIY person so im not planning on trying other brands. i cook with McCormicks and cant stand LorAnns. just thought id share. it turned out better than the few butter rums i have bought so im happy.
