It is a distinctive dish of Henan cooking style. Firstly, a special pot cover is laid over the fire to heat it to a high degree. Then some fresh eggs are whisked in a bowl. After that, some ham cubes, water chestnut cubes, dried shrimps, monosodium glutamate, cooking wine and brine are added to the bowl. Then some cooking oil is mixed in with the egg mixture and then put into the iron pot so as to heat it. Meanwhile, the egg mixture is slowly stirred as to prevent it from sticking to the pot.
When the eggs are nearly done, the heated pot cover is placed over the iron pot so as to bake them to the perfect degree. The surface of the eggs will become reddish yellow. This dish is not only bright in color but also fresh, tender and delicious.
