A bowl and a jug of water are part of the traditional hand-washing ritual before each meal, since foods are shared communally and eaten mostly with the right hand, though some items require both hands. Foods are served on a sandali, a low table, with everyone seated on a tashak, a cotton mattress that rests on a hand-woven rug. During the cold winter, Afghans stay warm by placing a manqkal, or charcoal brazier, under the table. The charcoal is burned beforehand and covered with warm ashes. In summer, when temperatures might reach 110 to 120 degrees, food is often served outdoors.
