Ingredients: Duck eggs, sodium hyroxide, and salt.
Thousand-year eggs. No, it did not take a thousand years to make them. In Chinese, these "pi dan", or preserved duck eggs, are covered in a mixture for weeks to months that raises their pH and turns up the flavors. You get this haunting dark egg. Rich in flavor, it generally goes in porridge or salads. Never judge an egg by its color. This egg will just judge you back.
