What Kangina Are:

Kangina is an ancient preservation technique still used in Afganastan today that makes use of clay. Produce is sealed within two clay bowls, and stored somewhere cool.

It is thanks to Kangina that even people in remote communities can still enjoy fresh produce in winter months. [1]

If stored somewhere cool, they will remain fresh for up to 6 months. This is because the vessels are a form passive controlled-atmosphere storage. Due to restricting the airflow and moisture, is is harder for microbes to thrive, but at the same time, the clay still supplies enough oxygen to keep the grapes alive. 2

How They are Made

After making bowls out of clay, they are left in the sun to bake. Once they are completely dried, they are ready to use. [3]

The produce (often grapes) are placed inside a bowl, and another bowl is placed on top and the seams are sealed with mud. [4]
