You can cook almost anything in a dutch oven with charcoal that you can cook in your home oven.
You just need to know The Rule of 3's
1- Take note of the size of your dutch oven. (i.e. 12")
2- Subtract 3 from the size (12-3=9) and add that many briquettes under your oven.
3- Add 3 to the size (12+3=15) and add that many briquettes on top of your oven.
This will give you approximately 325 degrees in your oven.
To increase the temperature, add 1 briquette above and 1 below, for every additional 25 degrees needed.
To decrease the temperature, remove 1 briquette above and 1 below, for every 25 degrees less you need.
