iso works just fine when you use it in cooking, but make sure extra f---ing sure, to make sure it is totally evaporated, as iso will kill you dead as jimi hendrix...
i usually give it an extra day evaporating if i'm gonna cook with it...
the end result is an awesome sticky goo ball, with power to spare...
if you are going to use ice hash/ pollen (pure trichs)/ iso hash/ earwax (co2 or butane extraction) the ratio's are about exactly the same for infusing it into your medium (butter, oil, glycerine ect)...
