Not only are Zeer pots cost-effective and relatively easy to assemble, but they were also first used in ancient Egypt to cool wine, so they’ve stood the test of time. Zeer pots, also known as pot-in-pot refrigerators, can be made with two differently-sized terracotta pots and coarse, wet sand. They’re perfect for those who lack land but want to cut down on electricity use. Before using one, make sure the pots are unglazed so the side will be porous enough to allow for evaporation. If you want to keep things as cool as possible, bury the pot so only the top is visible and accessible. It also helps to have the pot under shade and covered with either a clay dish or a wet cloth.
