This is a design dating back to as early as 2500 B.C. and the idea was somewhat abandoned with the invention of modern refrigeration. The results vary based on relative humidity in your area. The concept works best in hot desert area with low RH. The pots do not work in humidity above about 75%. This makes them ineffective in the summertime in many regions.
The sand should be damp to wet, NOT DRENCHED. The outer pot MUST be unglazed. The inner pot can be glazed but it is not necessary unless the food must stay dry like breads etc.
