2. Fill your own sausage. Generally, pork is the main ingredient, and bacon is put in the sausage skin. If the whole sausage is steamed in a pot, steam it for 25-30 minutes after the water is boiled, so that the meat inside is fully steamed and the purpose of high-temperature sterilization cooking is achieved. But the steaming time should not be too long, otherwise the casing will burst, which will lead to the leakage of sausage meat, affect the appearance and taste, and is not suitable for further preservation.
