When roasting a pig in the ground what do you use to cook it with?

You're describing a whole pig roast, often called a luau, ka lua pig, or lechon.

Here's what's used to cook it:

The "Oven":

* An underground pit: A hole is dug in the ground, lined with rocks, and heated with wood or charcoal.

* An insulated container: Sometimes a metal drum or large container is used instead of a pit. This can help regulate heat more evenly.

The "Wrap":

* Leaves: Banana leaves, ti leaves, or other large leaves are used to wrap the pig tightly, helping to retain moisture and impart flavor.

* Burlap or a heavy cloth: Sometimes used in addition to leaves for extra insulation.

Fuel:

* Wood: Different types of wood, like hickory or oak, add flavor to the meat.

* Charcoal: Charcoal is often used for its consistent heat and long burn time.

The Pig:

* A whole pig: A pig is typically used, but you can also roast a lamb or goat using the same method.

Additional Tips:

* Seasoning: The pig is typically seasoned with salt, pepper, and other herbs and spices.

* Time: Cooking a whole pig in the ground can take several hours, sometimes up to 8-10 hours.

* Traditional methods: In many cultures, this method of cooking is a traditional practice, often used for special occasions and celebrations.

It's important to note: This is a complex cooking method that requires careful planning and execution. It's best to follow the instructions of a trusted recipe or consult with an experienced cook.
