Step 1: Pour your cream into a mason jar with a proper fitting lid and shake.
Step 2: You will begin to see the whey and buttermilk separate.
Step 3: Pour off the buttermilk.
Step 4: Keep shaking and pouring until no more buttermilk can be shaken out.
Step 5: Put in a bowl. I used an old Earth Balance container. Cover with COLD water. I used the cold side of the tap. Use a spatula or wooden spoon to smash the rest of the buttermilk out. Dump water and repeat until the water comes off clear.
Step 6: If you want salted butter, add 1/3 to 1/2 a teaspoon to the butter and mix. Enjoy!
Like I said. It's easy. Being sufficient doesn't always mean back breaking work, I promise. Now milking the cow might be a little harder. I will let you know when I get one to milk. This is something the kids can do and love. Just use smaller jars with less cream. I will someday post how to make easy aprons for your wee ones.
