1, in terms of nutritional value, stew is indeed more nutritious and healthier. "Waterproof" stew is the highest quality. Through the high temperature of the water outside the stew pot and steam, indirectly make the temperature inside the stew pot rises to the boiling point, the essence of the raw materials all forced into the soup. Stew soup soup color is clear, more original flavor.

2, the practice of stew: stew using water heating method, the raw materials and water in the casserole (or stew pot), covered with a pot lid, placed in a large pot (the amount of water in the pot is lower than the casserole, in order to boil the water does not overflow into the casserole as appropriate). (If there are acidic ingredients in it, they need to be deodorized beforehand, and then various auxiliary ingredients and water should be added.) This water stewing method can make the heat of the raw materials and soup stable, the dish fresh flavor is not easy to lose, the soup is clear as water. The raw materials used for stew are basically more nutritious and nourishing. Stewed soup is generally a minimum of 4 hours or more.

3, the practice of soup: soup using direct heating method, is the raw materials and water into the casserole directly with the fire heating, large fire boil to the fire boil about 3 hours. Although the practice is simple, but into the effect of the Lei will not be as good as the water stew method. Moreover, in the process of boiling, the soup is constantly evaporating and water may need to be added depending on the situation. However, adding water in the middle of the process will definitely affect the flavor and color of the soup. So it's best to make sure you add enough water at one time.
