For one loaf of bread, which i make three or four times a week, I need three cups of flour. I was looking at a mill in Lehman’s which is hand cranked. I understand I’d need to pass the grain through a few times. You’re saying I shouldn’t do this?
The flour that you get will be unlike the flour that you buy and will behave differently when you make your bread. That is mainly because of particle size and ability to form gluten.
It's important to experiment before you need it, and know what you are going to have to put out in effort and what you will get.
