how do you make a 1000 year old egg
Century egg Century egg or Pidan (Chinese: 皮蛋; pinyin: pídàn), also known as preserved egg, hundred-year egg, thousand-year egg, thousand-year-old egg, millennium egg, skin egg and black egg, is a Chinese preserved food product and delicacy made by preserving duck, chicken or quail eggs in a mixture of clay, ash, salt, quicklime, and rice hulls for several weeks to several months, depending on the method of processing.[1]
Boiled egg Boiled eggs are eggs (typically chicken eggs) cooked with their shells unbroken, usually by immersion in boiling water. Hard-boiled eggs are cooked so that the egg white and egg yolk both solidify, while for a soft-boiled egg the yolk, and sometimes the white, remain at least partially liquid.
