Adventure 5: Buttermilk bread

This was my best bread to date. It tasted great, had a perfect consistency and was really tasty right out of the oven. I substituted buttermilk for the water, but otherwise left the standard recipe unchanged. The dough rose overnight, but unfortunately it had dropped back down by the morning, and I never had time to let it rise again before baking! Nevertheless it came out great. It baked in my gas oven, at 450 for the first 5 minutes, then down to 400 for the next 25 minutes or so.
