In this tutorial, we learn how to make butter. First, you will need some cream in a carton left out in the room for around 12 hours. After this, pour the cream out into a glass jar and put the lid on tightly. Now you will shake the jar nice and slowly. You want about 1 shake every second. Continue to do this for about 2-3 minutes. At first, you will notice the glass is covered with cream, but every time you shake the bottle, the butter fat will start to stick together into clumps. Continue to shake until you see butter, then use it how you would like and enjoy!
