I'm reading The Bread Builders: Hearth Loaves and Masonry Ovens in an attempt to come to grips with whether or not I'm going to be able to swing having a wood fire oven in my back yard. The downside of my back yard is that it is tiny and that most of it is several feet below the back door. I have a wood deck that is conveniently floor-height, but I have some concerns about placing a wood fire oven next to the deck.
Three of the big decisions that you have to make when picking out what sort of oven you're going to have are:
- How much are you going to cook at one time?
- Is this oven primarily for pizza or for bread?
- How often are you going to cook in it?
There's no oven that will easily support all of the range of options posed by the questions above without causing you to either waste a lot of money on wood, waste a lot of time heating the oven, destroy your oven after a few years, and/or give you an inferior product when you're done with it.
The more mass you give an oven, the longer it will take to heat, but the longer that the heat will last. For an oven you're going to use every day, you want a lot of mass, because it will hold much of the heat overnight. This means you have to use less fuel heating it up the next morning.
On the other hand, the same massive oven, used only a few times a week, would be a terrible pain, because it would take a tremendous amount of wood each time to heat it up, and you'll wait around forever for it to happen. Depending on the materials you've chosen, you may cause extra damage to the oven by causing the repeated expansion and contraction of something that was prepared to spend its life mostly expanded.
I can't imagine a better guide through these options than The Bread Builders. It's a fascinating read, and I'm looking forward to learning a lot more about the design and construction of this oven. Who knows, one day I may even build one. Wouldn't that be exciting?
