Question 1: the difference between old fire soup and stew soup.

Old fire soup, boil the water with high fire, and then heat it continuously with slow fire. Its soup will continue to boil, the soup is ready, and it can't be seen. Cooked meat and fat were scattered all over the floor. Pay attention to rich flavor

There are two kinds of stews: steaming stew and water stew. Stewed soup uses steam or boiled water to transfer heat, because the temperature is lower than that of direct fire or electric heating, so the soup in stewed soup will not boil violently, but the temperature will continue to be heated to 100 degrees. Because the cooking is not intense, the soup is crystal clear, and there is a circle of animal oil on the surface of the soup that has just been uncovered. In addition, steaming is much faster than boiling.

Question 2: Whether it's an old fire or a stew, you can't go wrong with a teapot. If it is a stew, you can use steam to stew the soup, which is mainly faster than water. Don't believe that slow stew is nutritious. You know, the longer the high temperature, the more serious the loss of food nutrition. It seems that many Laoguang recommend this brand of teapot. Anyway, my mother's generation used this brand of teapot.
