Ways to heat food outdoors
Bring a self-heating utensil to heat food without a fire, or even steam a delicious custard outdoors.
This self-heating tableware is composed of outer container, inner tank and heating sheet, before use, open the tableware container, and then unpack the heating sheet into the outer container, and then directly pour a certain amount of water on the heating sheet, and then only need to wait a few seconds, the heating sheet starts to heat up automatically, and then put the inner tank containing the food on the heating sheet to cover the lid, and then choose the appropriate heating time according to different food characteristics, a hot food will be presented in front of you.
It is reported that the main heat source of this self-heating tableware comes from this supporting heating sheet. This heating plate will undergo a special chemical reaction after encountering water, and the added water will be heated by its own heat, and then the food will be steamed by the principle of steaming.
At the same time, the heating sheet can continue to heat up to 30 minutes, not only coffee noodles, but also rice and custard such as more demanding foods.
Simply put, the principle of this heating sheet is very similar to the "baby warming sticker" used by citizens every day.
How outdoor cooking makes your own fire
If you don't have a fire and modern heating tools, you can make your own fire to heat the food.
1. Flint fire method
This method is the earliest method of fire extraction by humans, and its use may have been inspired by the phenomenon of sparks bursting when making stone tools. We can find a hard stone and make it a "flint", and hit the "flint" downward with the back of a knife or a small piece of steel to make the spark fall on the primer. When the ignition begins to smoke, slowly blow or fan it to ignite an open flame. If the "flint" does not make fire, you can find another stone and try again. Of course, not any stone can ignite the ignition, and the spark struck by the stone must have a certain amount of heat and duration to ignite the ignition. According to archaeological data, sparks from striking flint with pyrite can be used to make fire. The flint is covered with flammable velvet or charred cloth, and the blow ignites. There is a caveat here: the more angular the stone, the better it is against the flint, and when a hard stone has too rounded edges, it needs to be broken on the large stone so that sharp edges and corners appear.
2. Bow drill for fire
A bow is made by tying shoelaces, rope or belts with strong branches or pieces of bamboo. Wrap a dry stick around the bow and use it to spin rapidly on a small piece of hardwood. This will drill out black powder, and finally this black powder will smoke and produce sparks, igniting the ignition. Wearing the glass sheets on a flat wooden board can also generate heat and fire. When the vigorous friction is hot, the ignition material is blown on fire.
3. Rattan for fire
Find a trunk of a tree, split it at one end, and use something to stretch the crack, plug the ignition, use a rattan about two feet long to wear it behind the ignition, step on the trunk with both feet, and quickly pull the rattan left and right, so that it rubs and heats up and ignites the ignition. Two soft pieces of fire or bamboo can also be used to rub against each other to make the fire, and the bottom of the palm bark or coconut leaf is used as the ignition.
4. Drill wood for fire
Finding suitable wood for drill boards, dried aspen, willow, etc. will be a good choice because of their softer texture. Then find a suitable branch to make a drill, relatively hard can be, the conditions are not as harsh as the drill board. Then, drill the edge of the drill plate into a small inverted "V" shaped groove, and finally, put a flammable velvet or dead leaf under the drill plate, and then drill hard with both hands until the fire comes out.
