A hot box is a type of cookware that uses insulation to trap residual heat inside a pot or other cookware, allowing food to continue cooking without additional power. It can be made from a large box filled with insulation materials such as straw, foam, towels, rags, or a sleeping bag. Dishes like soups, stews, rice, and beans can be cooked in a hot box for several hours.
A hot box is basically a type of cookware that consists of a large box filled with insulating materials. This is used by a cook before heating food in a pot, typically with dishes such as stew or beans that are cooked for a fairly long time in a moist environment. The pot is then removed from a stove or other heat source and immediately placed in insulation inside the hot box. Once closed, the insulation traps heat inside the pot, allowing the food to continue cooking through the residual heat.
There are several ways a hot box can be made, although it is quite simple and fairly cheap to build. Almost any large box can be used as a starting point, although a cardboard box or large cooler are often the more popular choices. It is important that the box is large enough to accommodate insulation materials and the pot in which the food will be cooked. Since the heat needs to be properly trapped inside the hot box, it should also have a lid or otherwise be able to be closed somehow.
Different types of insulating material may be used inside a hot box, often depending on what is available and what can fit inside. Straw or foam can work as insulation, although they typically need to be dense enough to adequately retain heat and prevent it from escaping. Towels and rags may also be used, often wrapped around a pot to keep the heat in. If a large enough hot box is used, a sleeping bag can also be an excellent choice, especially since they are made with insulation to keep sleepers warm in an outdoor setting.
A hot box works by trapping residual heat inside a pot or other cookware. Food is placed inside a pot and this is heated using a stove or oven, much the same as it would be cooked. Before the dish finishes cooking, however, it is removed from the heat and immediately placed inside the box’s insulation. Over time, the residual heat inside the pot continues to cook the dish.
This type of cooking can take longer than a stove or oven, but requires no additional power after the initial heat-up. Dishes like soups and stews can simmer in a hot box for several hours, but only require heat and energy for one hour. Rice and beans can also be cooked this way; they can take longer than hob cooking, but still result in tender, well-cooked dishes.
