I know, sounds hard, but it require the machine to do all the work, while you hurry up and wait.
NP: buttermilk is a by-product if the butter making process; make the butter (and buttermilk!) with heavy cream. The buttermilk you get will be drinkable, unlike the buttermilk you but from the store. And if you accidentally buy too much cream, like I usually do, you can mix some with the buttermilk to make creme fraiche. It's like three recipes in one!
