Start with RAW COW'S CREAM - a decent food processor, and clean kitchen sink, large bowl and colunder! From Start to finsh this process takes about 20 mins. Cream spun at high speed, turns into thckened whipped cream (can be sweetened) than it turns breaks down farther into smaller particals and continues to spin..the fat breaks down and thins...the liquid is true buttermilk! Pour into cheesecloth and colunder, press butter, handle with your hands, squeeze gently under cold running water, salt and Enjoy! Save buttermilk for pancakes!!
