One of the challenges during a power outage is cooking meals. While there are many options, most require cooking outdoors using stove-type methods such as a rocket stove, BBQ grill, fire pit or camp stove. These methods work great, especially if they are coupled with a cast iron skillet or Dutch oven.
The problem, however, is that we can not predict or time when the power will go out. Nor can we predetermine how long the grid will be down; it may be hours or it may be days or even weeks. Not only that, what if the power goes out for a week during the coldest part of the year, with 10 inches of snow on the ground and a howling wind?
