How to prevent food from rotting, decaying, and spoiling for years?

Most foods cannot be stored and stored for long periods of time. Because after a certain period of time, the food goes into the process of decay. So we are not able to store many kinds of food in our food store.

Of course, our ancestors developed a method of preparing certain foods correctly and keeping them for a long time. For example, radish or greens can be kept for a long time and eaten by making gundruk or sinki. The taste of the tongue could be changed from time to time by making such meat as sukuti (dry meat). Soybeans can be bought (an original dish of the Limbu caste) and kept for months.
