Afghan cauldrons work on the principle of a pressure cooker - they save time by preparing the product faster and preserving vitamins. They differ from ordinary pressure cookers due to their dense metal, round shape and connecting device. The convenient handle on the clamping device and light weight allow you to use the cauldron on hikes and when going outdoors. It is convenient to stir food in a cauldron, just place it on its side and roll it on the surface, you do not need to open the lid often. The usable volume appears to be 65-80%, subject to the higher requirements for valve clogging conditions.
