Homemade BUTTER

My sister in law was telling me that she had her kids make butter from shaking baby food jars of cream until it turned into butter. This was 20 min or so of shaking. Fun but no fun if you know what I mean. So I bought a half gallon of heavy cream from Costco for about $4 and but it in my mixer. I mixed it for about 5-10 min. I turned into whipped cream--(it was so tempting to stop right there)--then it turned into butter. The butter clumped up and turned yellow. The buttermilk was there ready to be drained. So i drained the buttermilk and scooped up the butter. What fun! You can add 1/2 tsp of salt to the batch to give it some flavor if desired!
Who knew butter was so easy to make!
