The bread experiment

I made bread today. I have never been satisfied with my bread but everytime I work on it, it gets better. So far, I found better ways for my bread to proof (e.g. using spice bottles to hold a damp kitchen towel on top of my loaves) and to form a crust (leaving a pan of water in the oven and spraying the oven with a spray bottle). My main improvement so far, however, has been to make a sponge with water, flour, honey and yeast and let the whole thing rest overnight. This adds a lot of flavor and, by placing it in the fridge, I can easily split the task of making bread over a full day or even over night.

My utlimate goal would be to produce one of those really airy loaf of bread with a nice crust and large bubbles which would nicely catch droplets of melting butter. So far, I got the crust part covered although there is still part for improvement but tastewise and texturewise, I still have a lot to learn to produce the perfect baguette.
