There is an ancient technology coming from Egypt. Two pots are placed inside each other and the space left is filled with sand. Then water is poured in the sand. Food is placed inside the smaller pot and covered with a cloth. The water between the pots starts to evaporate which results the cooling of the inner pot and keeping the foods fresh. The same technique is introduced with different materials for our homes to preserve the fruits which are not suitable for refrigeration.
