Gangina is a traditional means of keeping grapes and other fruits fresh for several months, by sealing them in air-tight containers made of wet soil.
Grapes are tricky to keep fresh for long periods of time, even when refrigeration is available, but apparently Afghans have long been using an ancient method of keeping the soft fruits fresh for consumption in the winter months, when fresh fruits are otherwise hard to come by. Called gangina, this ingenious conservation technique involves sealing healthy grapes in a saucer-like container made of two layers of wet soil. The container is left in the sun to dry and then has to be kept in a cool place, away from direct sunlight. If stored properly, gangina containers can keep grapes picked in autumn fresh until next year’s spring season.
