1. processed mutton washed with water
2. put the mutton into the pressure cooker, add a sufficient amount of water, add enough at a time. My dad used a pressure cooker mainly because it was big enough, and did not use the pressure cooker's pressure function during the stewing process, the lid was just gently covered. If you have a large enough soup pot at home I think you can replace the pressure cooker
3. After boiling on high heat, you can start to bleach the soup surface of the blood foam and impurities. This is the most critical step, and my favorite reason for this lamb soup
4. Keep the heat low and cook for a while, and then add the peppercorns, dried chili peels and ginger at once. Peppercorns and ginger can not be missing, but the dried chili peppers according to personal preference increase or decrease. Although I put a lot of this, but I still do not feel spicy when I drink soup and eat meat, can not eat spicy on the omission of good
5. Cover the pot, need to be stewed on low heat for about an hour, halfway to put a salt
6. At the same time to prepare the two onions
7. Feel free to cut a little spare
