A pit oven is like a secret hole in the ground where you cook your food. You dig a big hole in the ground and then you fill the bottom with hot coals from a fire. It's like when you make s'mores and you squeeze the marshmallow between the two crackers over the fire. You put the food on sticks and then put the sticks on top of the coals in the pit oven. Then, you cover the whole pit with dirt to trap the heat inside. It's like when you put a lid on a pot when you're boiling water to make soup. The heat stays inside the pit and cooks the food slowly until it's really yummy and tasty. When the food is done, you take it out of the pit oven and enjoy!
