I was about to post how to make powdered butter along with the chemical process and a lot of it has do do with humidity and surface sealants. However your statement of "it works best if you rub her until she is steaming" made any chemical explanation totally without merit! I think you killed the thread but I congratulate you on the way you did it! You are a sick man but I admire you!!! :)
my opinion is this
if you want butter buy a cow
if you want all the things you think you paid for and DESERVE
buy a gun
hey tax chick really
shoot to kill
