The stewing method of blood swallow is basically the same as that of Bai Yan, but the stewing time is different. Stewing bird's nest requires at least one stew pot and a pot that can put the whole stew pot. Of course, ceramic pot or stainless steel pot will do.

Drain the soaked bird's nest, put it in a stew pot, cover it with appropriate amount of hot water, then put the whole stew pot into the pot, inject hot water to half the height of the stew pot, and then stew it with slow fire.

The water level of bird's nest with other condiments and boiled water (or other nutrient solution) in the stew shall not exceed 7 points (7/ 10) of the stew. Because the bird's nest will rise when stewing, and the water level will rise. If the water level is too high before stewing, it will easily tumble and cause waste.

Stew the bird's nest on water with slow fire, and the temperature in the pot will naturally be kept at about 80 degrees, which can reduce the protein damage of bird's nest and better preserve the nutrition and fragrance of bird's nest.
