Some notes on variations:
She makes a very wet dough that spreads out into a thinner loaf. This gives you a lot of surface area for a good crusty bread. For sandwiches, though, I add more flour and shape it into a soft oblong loaf that stands up more is a little less pocketed with air holes.
So if you're not sure what you like I would highly recommend giving yourself license to play around with the water to flour ratio. And however you do it, it's soul-soothingly amazing hot with butter.
