Cooking over a fire is a great way to prepare meats and fish and many vegetables much in the way we would cook over a stove.

However, there are things like pizza, bread, cookies, rolls, and all of the foods previously mentioned that really cook better in an oven due to the constant and enveloping heat.

To learn how to make that oven from scratch, watch the video below.

Nothing makes you look like you know what you're doing more than making and cooking in your own oven. Even if you don't know much else in the way of self-sufficiency, trading this knowledge with others can get you things they've prepared for that you haven't.

Oven cooking is great because it uses less fuel and allows the food to cook more evenly than cooking on an open flame. Bonus: Even when SHTF, you can still enjoy a great oven-roasted pizza.
