Chinese soup making technique:
Double boiling

If we try to melt chocolate in a pot over direct heat, the temperature goes up too high and burn the chocolate before melting it properly. The correct way to melt chocolate is to place the pot over another pot of boiling or hot water, the heat from the steam is lower and the chocolate melts evenly without burning. In the same way, to double boil soups mean to place the soup pot over another pot of boiling water. The soup is cooked using the heat from the boiling water and not directly from the original heat source. The Cantonese likes to double boil their soups and they use a special ceramic pot known as a double boiler. They believe that double boiling let the soup ingredients slowly release their nutrients into the soup. They also believe that the nutrients and flavour is "locked" in the soup when a ceramic double boiler is used. Double boiling is a fairly long cooking process. The average cooking time is about 4 hours. Refrain from opening the double boiler to check on the soup as this will bring down the temperature of the soup and affect the cooking. Anyway, there is little evaporation so the water will not dry out. The heat from the boiling water outside is also not high enough to cause a boil over. The only thing to check is that there is sufficient water for boiling.
