One of the many reasons why this cooking pot is so marvelous is due to its versatility. You see, when it comes to choosing an optimal heat source this is easy as there are tons of different options. You can go with your standard stovetop or oven use (if they are rated to be safe with your stovetop style and oven). Or, you can cook with your oven outdoors and do so over an open fire. In reality, this is the way they were intended to be used when the idea was first conceived for one. With a device in play to hold the oven over an open flame, this can produce excellent results.
But, perhaps an even better solution is to use charcoal briquettes. With this as your heat source, a more even and consistent temperature will result and your meals may improve, also.
