I purchased a "cow-share" in order to get raw milk. I pay $3 for a gallon of milk, actually cheaper than at the store. I provide my own glass gallon jugs and call ahead to let them know I'm coming, as long as it's before 10:30 am (that's when the truck picks up their milk). I then pour it off into quart measuring cups and let sit in the fridge overnight. The next morning I scoop off the cream and place in a separate pint Mason jar and make ice cream, butter, whatever I need. These are pastured cows and organic. I bought a half-gallon of organic milk from the store not so long ago and paid almost $5 for "organic" milk, that, to me, was NOT organic, i.e., ultra-pasteurized and homogenized. I was sorely disappointed. I looked up the percentages for making half and half (10.5% to 18%), heavy/whipping cream (35% to 40%) and whole milk (3.25% to 4%). I then do the calculations and add that amount of cream in ounces back into the now skim milk. It tastes EXACTLY as it should since I have drank a great amount of all of them over the years.
