When baking bread, the amount of humidity in the air makes a big difference in how the crust of the bread comes out. With the right amount of humidity you get a really good crunchy crust. We used to spray water into the oven when baking to get it just right. Also makes the strudel dough go nice and crunchy. My great aunt used to make the best strudel. With her it was an all day affair, because if you are going to make up a batch, you may as well make enough for a whole army. The smell in the kitchen would be absolutely heavenly.
