Well, I tried mak­ing some home­made but­ter.  And, maybe dis­as­ter was the wrong word… Appar­ent­ly, my biggest mis­take was using heavy cream that was “ultra pas­teur­ized.”  It turned out like flat whipped cream sludge.  It prob­a­bly could have been used as a prop in a movie for some sort of plas­ma.  Maybe I was­n’t churn­ing strong or fast enough… Next attempt will be using my food proces­sor, as in the below video.  Even­tu­al­ly, should I be suc­cess­ful at this, I may buy a but­ter churn from Lehmans to be kept at a BOL in the event of an off grid expe­ri­ence.
