Thought I had this posted here but couldn't find it so I brought it over from PF
1 gallon raw milk. Dipped out the cream from the top of each 1/2 gallon jar. Put it in the food processor and let run on low for about 7 minutes.
It started to break.
Strained it then ran it some more.
Ended up with this.
Added a pinch or so of sea salt and I've got the real deal sweet cream butter.
