Equipment

• Kazan

  A kazan is the heavy, round-bottomed cauldron of Central Asian cooking: cast iron or thick aluminum, built for plov (pilaf), shurpa, and open-fire feasts from Uzbekistan to the Caucasus.

• Microwave oven

  The microwave oven cooks by exciting water molecules with radio-frequency waves, invented after a radar engineer's chocolate bar melted in his pocket in 1945.

• Refrigerator

  The refrigerator is the appliance that quietly rewrote how humanity eats, holding food near 37°F/3°C to slow the microbes and enzymes that spoil it, making fresh food storable, shopping weekly, and leftovers possible.
