An earthen oven is a traditional cooking structure made from natural materials like clay, mud, and straw. These ovens are often shaped like a dome and are designed to retain heat, allowing for efficient cooking. They are commonly used in various cultures around the world for baking bread, roasting meats, and preparing other dishes. The construction of an earthen oven typically involves building a base and then layering the earthen materials to form the dome. Once completed, the oven is heated with wood or other fuels, creating a hot environment ideal for cooking. This method of cooking is not only energy-efficient but also imparts a unique flavor to the food, making it popular in many culinary traditions, including those of Mexico and India.
