HOW DOES A BUTTER CHURN WORK?
While this is a simple device, we haven’t explained how exactly cream turns into butter. What is the science behind this? Well, it is rather straightforward as well. During the churning process, the cream gets vigorously stirred up. The agitation breaks the membranes of fat molecules, making them clump together. As large clusters of fat collect, they begin forming a network. Also, the churning process generates bubbles of air that trap the liquid and produce the foam separating one substance from another. All this clumped fat is butter, whereas the liquid separated from it is called buttermilk. But how about butter that is made from milk? The truth is that it is not made from milk. Whole milk has to sit until fat molecules float up and create a thick layer on the surface. That’s actually cream that needs to be gathered and then turned into butter through the churning process.
